Forum Exploits?
 

I'm just wondering if there are currently any vBulletin exploits in (vBulletin 4.2.0 Patch Level 2http://version.vbulletin.com/version...&id=VBF899740A)

I'm currently using that and my site was recently compromised so I'm wondering if there are any popular exploits that may have been responsible that I hadn't known about
