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

Product:              CCK (Drupal third-party module)
Publisher:            Drupal
Operating System:     UNIX variants (UNIX, Linux, OSX)
                      Windows

- - ------------SA-2008-048 - SITE DOCUMENTATION - PRIVILEGE ESCALATION-------


  * Advisory ID: DRUPAL-SA-2008-048
  
  * Project: CCK (third-party module)

  * Version: 5.x

  * Date: 2008-Sep-04

  * Security risk: Not critical

  * Exploitable from: Remote

  * Vulnerability: Cross site scripting

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

The contributed module Site Documentation intends to assist developers and
administrators when they start working with a new site by showing them
information from the database.

All users with the "access content" permission are able to use the module 
to list arbitrary tables from the database. In typical scenarios, both 
anonymous and authenticated users have the "access content" permission. 

Access to arbitrary tables enables an attacker to impersonate users by 
using SESSION IDs obtained from the database.  An attacker could use 
specifically crafted URLs to gain access to additional private information, 
including, but not limited to, all usernames, password hashes, and e-mail 
addresses.

- - ------------VERSIONS AFFECTED------------
    
  * CCK for Drupal 5.x prior to 5.x-1.8

Drupal core is not affected. The CCK RC releases for Drupal 6 are not 
affected. If you do not use the contributed CCK module on a Drupal 5 site,
there is nothing you need to do.

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

Install the latest version:

  * CCK 5.x-1.8 5.x-1.8 had two critical bugs
  * CCK 5.x-1.9 hotfix release - includes security fix and these critical 
    issue fixes.

See also the CCK project page.

- - ------------NOTE------------

If your theme uses field templates, you will need to manually change the 
function phptemplate_field (or possibly THEME_NAME_field) in your theme's
template.php:
change:
'label' => t($field['widget']['label']),
to:
'label' => check_plain(t($field['widget']['label']))


- - ------------REPORTED BY------------

The cross site scripting issue was reported by Peter Wolanin from the Drupal
security team.
