vBulletin HTML Injection & XSS Vulnerabilit

Code

                                                source: http://www.securityfocus.com/bid/30134/info

vBulletin is prone to an HTML-injection vulnerability because the application fails to properly sanitize user-supplied input before using it in dynamically generated content.

Attacker-supplied HTML and script code would run in the context of the affected browser, potentially allowing the attacker to steal cookie-based authentication credentials or to control how the site is rendered to the user. Other attacks are also possible.

Versions prior to vBulletin 3.7.2 PL1 and 3.6.10 PL3 are vulnerable.
