Pinata - A CSRF POC HTML Generation tool.

After much laziness I have finally completed the CSRF tool. I have named it Pinata.

Overview:

- The tool will generate proof of concept CSRF HTML given an HTTP request. It will automatically check whether it is a GET or a POST request and with further validation for standard POST and Multipart/form POST.
- The tool will then create an HTML corresponding to the type of the request.
- The GET CSRF HTML includes IMG tag with SRC set to the URL being tested.
- The POST CSRF HTML is created with auto submit java script form with names and values from the HTTP request.


Working:

- It is Python based tool. Needs Python installed – I have developed it on Python 2.6 and recommend using that version.
- The tool consists of three files, piñata.py, markup.py and CSRFBody.txt.
- To install it create a new directory like C:\Pinata and copy all three files to it.
- Piñata.py is the main file and should be run to generate the HTML.
- Markup.py is called by piñata.py to generate HTML, I did not develop it and do not take any credit for it - however I would like to thank the developer, it made my life much easier. NOTE:It should not be alerted.
- CSRFBody.txt holds the HTTP request.
- To use the tool go to vulnerable page, create a request, capturing the HTTP request in the proxy. Copy this request and paste it in CSRFBody.txt and then saving and closing CSRFBody.txt
- Run the tool by going to command line and typing C:\Pinata\pinata.py
- It should generate the HTML file in C:\Pinata\


Future Direction

- I look forward to your suggestions.
- Perhaps some features to beat referer header based CSRF protection.
- This is essentially a hack so I will work towards cleaning up the current code.


Questions:
