Discussion
vBulletin 'Profile Customization' Feature HTML Injection Vulnerability
vBulletin is prone to an HTML-injection vulnerability because it fails to properly sanitize user-supplied input before using it in dynamically generated content.
Successful exploits will allow attacker-supplied HTML and script code to 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.
vBulletin 4.0.8 is vulnerable; other versions may also be affected.
Note: This issue can be exploited only when the 'Profile Customization' feature is enabled and affects only Internet Explorer 6(IE6) browser.
