SQLmap 0.8 and SOAP based Web-Services

I Love SQLmap , it's clean, fast, super efficient, fully automated and get's the job done when a POC is needed.

Lately I was pen-testing SOAP Web-Services, and I came to learn that SQLmap wasn't aware of SOAP syntax.

Being the lazy hacker I am the thought of manually testing the entire application using SOAPUI and some tweaking gave me a chill ,So, I have fired up my Python and patched a small mod to let SQLmap do it's magic on SOAP request too.

Basically, the mod instructs SQLmap to parse XML input into parameter-value map in the same manner that SQLmap was parsing GET/POST parameters.

In the same manner of looking for &parametera=valueA&paramB=valueB.. etc. SQLmap now looks into the XML request and parse it to Child and Value (current mod omit the attributes)

That said, if you wanna get some serious injection and SOAP'n dirty (Ha!) try this patch and let me know ;)

There are three files to patch for version 0.8: agent.py, common.py and traget.py
Happy Hunting ;)
