- The remote host is running vBulletin, a web based bulletin board system
- written in PHP.
-
- The remote version of this software seems to be prior or equal to version 2.2.9.
- These versions are vulnerable to a cross-site scripting issue,
- due to a failure of the application to properly sanitize user-supplied
- URI input.
-
- As a result of this vulnerability, it is possible for a remote attacker
- to create a malicious link containing script code that will be executed
- in the browser of an unsuspecting user when followed.
-
- This may facilitate the theft of cookie-based authentication credentials
- as well as other attacks.
-
- Solution : Upgrade to latest version
