SA-CONTRIB-2009-032 - Webform - Cross-site scripting - Security-news

3 Jun 2009


      * Advisory ID: DRUPAL-SA-CONTRIB-2009-032
  * Project: Webform (third-party module)
  * Versions: 5.x, 6.x
  * Date: 2009-June-03
  * Security risk: Moderately critical
  * Exploitable from: Remote
  * Vulnerability: Cross-site scripting
-------- DESCRIPTION  
---------------------------------------------------------
The Webform module provides a node type which is typically used to enable
site visitors to fill in questionnaires, contact or request/registration
forms, surveys, polls, or other forms on a Drupal site. When displaying the
results of Webform submissions, the module does not properly filter user
entered data, leading to a cross-site scripting [1] (XSS) vulnerability on
sites with a specific configuration of input formats that would normally be
safe. Such an attack carried out against a sufficiently privileged user may
lead a malicious user to gain administrator access to the site.
-------- VERSIONS AFFECTED  
---------------------------------------------------
* Versions of Webform for Drupal 5.x prior to 5.x-2.7
  * Versions of Webform for Drupal 6.x prior to 6.x-2.7
Drupal core is not affected. If you do not use the contributed Webform
module, there is nothing you need to do.
-------- SOLUTION  
------------------------------------------------------------
Install the latest version:
  * If you use Webform for Drupal 5.x, upgrade to Webform 5.x-2.7 [2].
  * If you use Webform for Drupal 6.x, upgrade to Webform 6.x-2.7 [3].
