Raptor OpenSource Web application firewall and bypass Techniques

[r41d3n 0]

I write this tool to test some payloads and to get deep understand about how  bypass WAF

 

 Raptor is a Web application firewall made in C, uses DFA to block SQL injection, Cross site scripting and path traversal.

Did you take this in account .https://blog.qualys.com/wp-content/uploads/2012/07/Protocol-Level Evasion of Web Application Firewalls v1.1 (18 July 2012).pdf

bit dated however I have incorporated quite a few of the techniques there's also a good paper out this year from blackhat on waf evasion I forgot it's name but it also has a github. HTTP Parameter polution is also a good vuln to smuggle shady payloads in. I haven't really tried array injection yet but I mean a lot of php sites are vulnerable to it.

Good programming will stop ether dead in their tracks....  Repeat after me, "On the Internet any user supplied data is rogue, unless proven otherwise....".

 

I think this is a false sense of security and measures need be taken at the web app dev. level or NOTHING can stop SQLI or any exploits.

 

 

EDIT: but with that said, I've seen some pretty 1337 stuff done with null terminated strings in PHP. Seen  people exploit PHP functions (regEx engines, stored procedures) exploiting the underlying C code.
