AusCERT Security Bulletin Summary
---------------------------------
Product: Menu Access (Drupal Third party module)
Publisher: Drupal
Operating System: Windows
UNIX variants (UNIX, Linux, OSX)
Impact/Access: Cross-site Scripting -- Remote with User Interaction
Resolution: Patch/Upgrade
Original Bulletin:
http://drupal.org/node/1147194
- --------------------------BEGIN INCLUDED TEXT--------------------
* Advisory ID: DRUPAL-SA-CONTRIB-2011-019
* Project: Menu Access [1] (third-party module)
* Version: 6.x
* Date: 2011-MAY-04
* Security risk: Moderately critical (definition of risk levels) [2]
* Exploitable from: Remote
* Vulnerability: Cross Site Scripting
- -------- DESCRIPTION ------------------------------------------------------
The Menu Access module provides global, menu specific, and per menu item
security permissions by role and user account.
The Menu Access module contains a cross site scripting (XSS) [3]
vulnerability that can be exploited when a specially formatted menu
description is viewed. This could result in administrative account compromise
leading to web server process compromise.
This vulnerability is mitigated by the fact that the attacker must have a
role with the 'administer menu' permission which should generally only be
granted to trusted roles.
- -------- VERSIONS AFFECTED ------------------------------------------------
* Menu Access module for Drupal 6.x versions prior to 6.x-1.9 [4]
Drupal core is not affected. If you do not use the contributed Menu Access
[5] module, there is nothing you need to do.
- -------- SOLUTION ---------------------------------------------------------

Menu Access 6.x-1.9 [6]
