YaBB SE Cookie Authentication Bypass

high Nessus Plugin ID 30054

Language:

Synopsis

The remote web server contains a PHP application that suffers from an authentication bypass vulnerability.

Description

The remote host is running YaBB SE, a web-based forum written in PHP.

The version of YaBB SE installed on the remote host allows use of a cookie to bypass authentication. A remote attacker can leverage this issue using a specially crafted value for the cookie to gain access as any user, including the administrator, which could in turn lead to execution of arbitrary commands on the affected host, subject to the privileges under which the web server operates.

Solution

Use another product since YaBB SE is no longer supported.
