A proof of concept for Joomla's CVE-2015-8562 vulnerability (Object Injection RCE)
This PoC is the second version of the implementation hosted at exploit-db.
-Fixed (regenerate session)
-Added the option to switch from X-Forwarded-For to User-Agent method
-Added the option to switch from a python reverse shell to a bash one
-Added catching exception for missing http schema and script termination
-Edited for a better usage, better messages and colors
-TODO: adding msf support

In December 2015 a new vulnerability was found in Joomla. It allows a remote attacker to exploit PHP object injection attacks and execute arbitrary PHP code via the HTTP User-Agent header.
This vulnerability target Joomla 1.5.0 through 3.4.5 and PHP version before 5.4.45 (including 5.3.x), 5.5.29 or 5.6.13 CVE-2015-6835.
I've made this blog post explaining the vulnerability.
