Authentication: Not required to exploit.
Multiple Open Redirect vulnerabilities in vBulletin version 4.1.3 and below allow remote attackers to redirect users to arbitrary web sites and conduct phishing attacks via the “url” parameter. By appending ?url=http://attackersite.com to any number of pages, the user will be redirected to a potentially dangerous site. This is particularly interesting when used on the registration form or the password reset form.
