Technical Analysis

Vuln affects versions 5.0.0 to 5.5.4 and is weaponized in the form of a Metasploit module: https://github.com/rapid7/metasploit-framework/pull/13512
Credit to Charles Fol for discovery and Zenofex for fast analysis and slick weaponization.

I keep thinking that it’s unlikely enterprises use vBulletin and this must be more of a risk to small- and medium-sized businesses, but looking at some of the companies that are said to be vBulletin customers, I suppose that’s not necessarily true. Article on in-the-wild exploitation here.
