The remote web server contains a CGI application that is prone to
cross-site scripting attacks.
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.
Upgrade to YaBB version 2 RC2 or greater.
