PHP Hardening Phuzzer

It uses feedback from xdebug and strace to generate random and arbitrary input parameters to a PHP script and find code paths which lead to exploitation. Primarily it's designed to scan for vulnerabilities in PHP scripts which are web accessible but not meant to be run directly.

Features

• Detect input parameters, _GET, _POST, _REQUEST, _COOKIE and _FILES
• Generate random input parameters
• Find unique code paths
• systemcall tracing with strace and dtruss, tested on Linux & OSX
• PHP function call tracing, using Xdebug

TODO

• Make it suck less
• Analysis of collected Phuzz cases/traces, automatic exploit generation
• dtrace and systemtap support

Example

The first request is made to analyse which inputs the script uses.

[Thu Sep  8 17:36:00 2016] 127.0.0.1:36996 [200]: /rce1.php

It then generates random values for the required parameters, and finds all the PHP and system calls that.

[Thu Sep  8 17:36:00 2016] 127.0.0.1:36998 [200]: /rce1.php?cmd=SWGAGI55
<webroot>/rce1.php
	 system ( 'SWGAGI55' )

syscalls:
	 stat ( "/usr/local/sbin/SWGAGI55", 0x7ffff9f76140 )
	 stat ( "/usr/local/bin/SWGAGI55", 0x7ffff9f76140 )
	 stat ( "/usr/sbin/SWGAGI55", 0x7ffff9f76140 )
	 stat ( "/usr/bin/SWGAGI55", 0x7ffff9f76140 )
	 stat ( "/sbin/SWGAGI55", 0x7ffff9f76140 )
	 stat ( "/bin/SWGAGI55", 0x7ffff9f76140 )
	 stat ( "/usr/games/SWGAGI55", 0x7ffff9f76140 )
	 stat ( "/usr/local/games/SWGAGI55", 0x7ffff9f76140 )
