YaBB YaBB.pl usersrecentposts Action username Parameter XSS

medium Nessus Plugin ID 17305

Synopsis

The remote web server contains a CGI application that is prone to cross-site scripting attacks.

Description

The installed version of YaBB (Yet Another Bulletin Board) on the remote host suffers from a remote cross-site scripting flaw due to its failure to properly sanitize input passed via the 'username' parameter and used as part of the 'usersrecentposts' action. By exploiting this flaw, a remote attacker can cause arbitrary code to be executed in a user's browser in the context of the affected website, resulting in the theft of authentication data or other such attacks.

Solution

Upgrade to YaBB version 2 RC2 or greater.
