- --------------------------BEGIN INCLUDED TEXT--------------------
- ------------SA-2008-014 - USERPOINTS - CROSS SITE REQUEST FORGERY------------
* Advisory ID: DRUPAL-SA-2008-014
* Project: Userpoints (third-party module)
* Version: 4.7.x, 5.x-2.x, 5.x-3.x
* Date: 2008-January-30
* Security risk: Not critical
* Exploitable from: Remote
* Vulnerability: Cross site request forgery
- ------------DESCRIPTION------------
Userpoints is a system for keeping track of points earned on a site. It can be
used to reward users for contributions to a community and also for ecommerce
transactions.
The Drupal Forms API protects against cross site request forgeries (CSRF),
where a malicious site can cause a user to unintentionally submit a form to
another site where they are authenticated. The point moderation form does not
follow the standard Forms API submission model and is therefore not protected
against this type of attack. A CSRF attack may result in the acceptance or
decline of points which were in moderation.
- ------------VERSIONS AFFECTED------------
* Userpoints for Drupal 4.7.x before Userpoints 4.7.x-2.3
* Userpoints for Drupal 5.x before Userpoints 5.x-3.3 or 5.x-2.16
Drupal core is not affected. If you do not use the contributed Userpoints
module, there is nothing you need to do.
- ------------SOLUTION------------
Install the latest version:
* If you currently use Userpoints 4.7.x-2.x upgrade to Userpoints 4.7.x-2.3 [
http://drupal.org/node/216028 ].
* If you currently use Userpoints 5.x-2.x upgrade to Userpoints 5.x-2.16 [
http://drupal.org/node/216027 ].
