vBulletin < 3.6.5 .swf ActionScript XSS

Medium

Synopsis

The remote host is vulnerable to a Script Injection attack.

Description

The version of vBulletin installed on the remote host fails to properly sanitize user-supplied input. Given this, the application is prone to a file upload flaw. An attacker exploiting this flaw would create a post that includes a malicious .swf file attachment. The malicious .swf file would be uploaded to the target server. Users viewing the post and executing the .swf file would be vulnerable to a loss of confidential data.

Solution

Upgrade to version 3.6.5 or higher.
