- **`py-collaborator`** - Poor man's Burp-Collaborator equivalent. A project offering mitmproxy/proxy2 plugin for injecting pingback URLs into processed HTTP(S) requests, and server part capable of handling Out-of-band incoming requests triggered by some Load Balancer/Reverse-Proxy/Caching-Proxy/other fetchers misconfigurations (alike to _Server-Side Request Forgery_ condition). Implementation based on terrific research of James 'albinowax' Kettle [Cracking the Lens](https://portswigger.net/kb/papers/crackingthelens-whitepaper.pdf).

- **`reencode.py`** - ReEncoder.py - script allowing for recursive encoding detection, decoding and then re-encoding. To be used for instance in fuzzing purposes. Imagine you want to fuzz XML parameters within **PaReq** packet of 3DSecure standard. This packet has been ZLIB compressed, then Base64 encoded, then URLEncoded. In order to modify the inner XML you would need to peel off that encoding layers and then reaplly them in reversed order. This script allows you to do that in an automated manner.

## py-collaborator - A Python's version of Burp Collaborator (not compatible)
|
||||||
|
---
|
||||||
|
|
||||||
|
This is a client-server piece of software that implements technique discussed by James 'albinowax' Kettle at his [Cracking the Lens](https://portswigger.net/kb/papers/crackingthelens-whitepaper.pdf) whitepaper.
|
||||||
|
|
||||||
|
The tool of trade comes in two flavors:
|
||||||
|
|
||||||
|
### 1. Client proxy plugin
|
||||||
|
---
|
||||||
|
|
||||||
|
Implemented for [mitmproxy](https://github.com/mitmproxy/mitmproxy) and for my own [HTTP/S proxy2](https://github.com/mgeeky/proxy2).
|
||||||
|
|
||||||
|
|
||||||
|
#### mitmproxy
|
||||||
|
|
||||||
|
One can use it with **mitmproxy** by loading a script file:
|
||||||
|
|
||||||
|
```
|
||||||
|
$ mitmproxy -s py-collaborator-mitmproxy-addon.py
|
||||||
|
```
|
||||||
|
|
||||||
|
After that,
|
||||||
|
a) go to your favorite browser
|
||||||
|
b) set up it's proxy so it points on **mitmproxy**'s listening interface and port
|
||||||
|
c) Load up mitmproxy's certificate by browsing to **http://mitm.it** and selecting your option (int Firefox - you can directly go to the: [http://mitm.it/cert/pem](http://mitm.it/cert/pem))
|
||||||
|
d) Select trust checkboxes.
|
||||||
|
|
||||||
|
Then, when in **mitmproxy** interface - type in **'E'** to go to Events log and look for following outputs:
|
||||||
|
```
|
||||||
|
info: Loading script /mnt/d/dev2/py-collaborator/py-collaborator-mitmproxy-addon.py
|
||||||
|
info: Initializing py-collaborator-mitmproxy-plugin.
|
||||||
|
info: Connecting to MySQL database: root@<YOUR-IP> ...
|
||||||
|
info: Connected.
|
||||||
|
...
|
||||||
|
Injected pingbacks for host (login.live.com)
|
||||||
|
...
|
||||||
|
```
|
||||||
|
|
||||||
|
If you spot those lines, the injecting plugin is working and you can now browse your target webapplications. Every request met will get injected headers, as well as there will be couple of additional hand-crafted requests in the background going on.
|
||||||
|
|
||||||
|
|
||||||
|
#### proxy2
|
||||||
|
|
||||||
|
Although **proxy2** is very unstable at the moment, one can give it a try by running:
|
||||||
|
|
||||||
|
```
|
||||||
|
$ ./proxy2.py -p py-collaborator-mitmproxy-addon.py
|
||||||
|
```
|
||||||
|
|
||||||
|
After that,
|
||||||
|
a) go to your favorite browser
|
||||||
|
b) set up it's proxy so it points on **proxy2**'s listening interface and port
|
||||||
|
c) Load up proxy2's certificate by browsing to **http://proxy2.test**
|
||||||
|
d) Select trust checkboxes.
|
||||||
|
|
||||||
|
|
||||||
|
|
||||||
|
### 2. Server part
|
||||||
|
---
|
||||||
|
|
||||||
|
Just as Burp Collaborator needs to listen on ports such as 80, 443, 8080 - our server will need too. In order to handle properly 443/HTTPS traffic, we shall supply to our server wildcard CA certificate, that can be generated using **Let's Encrypt's certbot**.
|
||||||
|
|
||||||
|
1) One will need to start a MySQL server, no need to create database or initialize it anyhow.
|
||||||
|
2) Then, we need to configure all needed informations in **config.json** file.
|
||||||
|
3) Having properly filled config.json - we can start up our server:
|
||||||
|
|
||||||
|
```
|
||||||
|
$ python3.7 py-collaborator-server.py
|
||||||
|
```
|
||||||
|
|
||||||
|
Server while running, will handle every **Out-of-band** incoming requests having UUID previously inserted to database, during proxied browsing. Such found correlation will be displayed as follows:
|
||||||
|
|
||||||
|
```
|
||||||
|
hostname|23:55|~/dev/py-collaborator # python3.7 py-collaborator-server.py -d
|
||||||
|
|
||||||
|
:: Cracking the Lens pingback responding server
|
||||||
|
Responds to every Out-of-band request correlating them along the way
|
||||||
|
Mariusz B. / mgeeky '16-18, <mb@binary-offensive.com>
|
||||||
|
|
||||||
|
