Title: VBulletin Cross-Site Scripting Vulnerability
Severity: HIGH
Description:
vBulletin is commercial web forum software written in PHP and back-ended by a MySQL database. It will run on most Linux and Unix variants, as well as Microsoft operating systems.
vBulletin does not filter HTML tags from URL parameters, making it prone to cross-site scripting attacks.
As a result, it is possible for a remote attacker to create a malicious link containing script code which will be executed in the browser of a legitimate user, in the context of the website running vBulletin.
This issue may be exploited to steal cookie-based authentication credentials from legitimate users of the website running the vulnerable software. Cookie-based authentication credentials may be used by the attacker to hijack the session of the legitimate user.
Affected Products:
- VBulletin VBulletin 2.0.0 rc 2
