YaBB YaBB.pl usersrecentposts Action username Parameter XSS

This script is Copyright (C) 2005-2014 Tenable Network Security, Inc.


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.

Risk factor :

Medium / CVSS Base Score : 4.3

CVSS Temporal Score : 3.7
