[IT-SecurityNotifies] [Security-news] SA-CONTRIB-2010-048: CiviRegister - Cross Site Scripting

[security-news AT drupal.org]

  * Advisory ID: DRUPAL-SA-CONTRIB-2010-048
  * Project: CiviRegister (third-party module)
  * Version: 5.x, 6.x
  * Date: 2010-May-12
  * Security risk: Critical
  * Exploitable from: Remote
  * Vulnerability: Cross Site Scripting

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

The CiviRegister module replaces the standard Drupal user registration form
with a CiviCRM Profile form configured to create users. Notifications on the
Profile's administrative page include unsanitized data obtained from the URL.
A malicious user could create a special link which would inject arbitrary
HTML into the resulting page, if clicked by a Drupal user with 'administer
CiviCRM permissions.' Exploiting this vulnerability could allow a malicious
user to gain the permissions of the targeted user.

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

  * Versions of CiviRegister for Drupal 6.x prior to 6.x-1.1
  * Versions of CiviRegister for Drupal 5.x.

Drupal core is not affected. If you do not use the contributed CiviRegister
[1] module, there is nothing you need to do.

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

Install the latest version.

  * If you use CiviRegister for Drupal 6.x upgrade to CiviRegister 6.x-1.1 [2]
    or any later version.
  * If you use the CiviRegister module for Drupal 5.x, you should uninstall
    CiviRegister. CiviRegister and CiviCRM are no longer supported for Drupal
    5.x.
