        AusCERT Security Bulletin Summary
        ---------------------------------

Product:           Automated Logout (Drupal third-party module)
Publisher:         Drupal
Operating System:  Windows
                   UNIX variants (UNIX, Linux, OSX)
Impact/Access:     Cross-site Scripting -- Existing Account
Resolution:        Patch/Upgrade

Original Bulletin: 
   http://drupal.org/node/667094

- --------------------------BEGIN INCLUDED TEXT--------------------

  * Advisory ID: DRUPAL-SA-CONTRIB-2009-114
  * Project: Automated Logout (third-party module)
  * Version: 6.x
  * Date: 2009-December-23
  * Security risk: Moderately Critical
  * Exploitable from: Remote
  * Vulnerability: Cross Site Scripting

- -------- DESCRIPTION ---------------------------------------------------------

This module provides a site administrator the ability to log users out after
a specified time of inactivity. The module does not sanitize some of the
user-supplied data before displaying it, leading to a cross-site scripting
(XSS [1]) vulnerability. Users who can take advantage of this vulnerability
could gain administrator access to a site. This vulnerability is mitigated by
the fact that the attacker must have a role with the 'administer autologout'
permission.

- -------- VERSIONS AFFECTED ---------------------------------------------------

  * Automated Logout module 6.x-1.6 and prior versions on the 6.x-1.x branch
  * Automated Logout module 6.x-2.2 and prior versions on the 6.x-2.x branch

Note that the Drupal 5 version of the Automated Logout module is also
affected, but the attacker must have a role with the 'administer site
configuration' permission. The 'administer site configuration' permission is
inherently unsafe and should only be granted to trusted users; therefore,
this issue is not considered a security vulnerability for Drupal 5 (see
http://drupal.org/node/475848). Drupal core is not affected. If you do not
use the contributed Automated Logout [2] module, there is nothing you need to
do.

- -------- SOLUTION ------------------------------------------------------------

Install the latest version:
  * If you use the Automated Logout module for Drupal 6.x, upgrade to either
    Automated Logout 6.x-1.7 [3] or Automated Logout 6.x-2.3 [4]

See also the Automated Logout module project page [5].
