his exploit owns any forum based on vBulletin 5. All versions. Still there is no CVE or patch. On this moment vBulletin 5.0.0 beta 21 is the last version and its affected, including the vendor's site. Wow! 5.0.0 <= Beta 21 (2012-12-19) http://1337day.com/exploit/description/20002
I haven't seen anything on the vb forums talking about this, but I haven't really been on a computer the last 5 days.
