# vBulletin 4.0.x => 4.1.2 AUTOMATIC SQL Injection exploit

# Author: D35m0nd142, <d35m0nd142@gmail.com>

# Google Dork: inurl:search.php?search_type=1

# Date: 02/09/2014

# Vendor Homepage: http://www.vbulletin.com/

# Tested on: vBulletin 4.1.2

# Usage: perl exploit.pl <http://target> <valid username> <valid passwd> <existent group> <userid to hack>

# Tutorial video: https://www.youtube.com/watch?v=_jec3nkoYFc

# IMPORTANT: At the first execution of the exploit I suggest you to login and logout to the forum (with a browser), then running it in order to allow the exploit to retrieve the correct security token to use. If you run more than one time the exploit, it may not get the security token because of the previous session's cookies and so you may have some problems retrieving the correct information. THE SOLUTION IS to copy the correct security token previously found (usually at the first run) and paste it into the source code where I wrote 'HERE'.
