By Drupal Security Team on
- Advisory ID: DRUPAL-SA-CONTRIB-2012-102
- Project: Ubercart AJAX Cart (third-party module)
- Version: 6.x
- Date: 2012-June-13
- Security risk: Less critical
- Exploitable from: Remote
- Vulnerability: Information Disclosure
Description
This module enables you to replace the default Ubercart shopping cart block with an AJAX-enabled one.
The module includes the user's current session ID in one of its JavaScript settings keys on every page load which could be intercepted if the user's connection is not over SSL.
This vulnerability is mitigated by the fact that an attacker must gain read access to the HTML output of a page with the uc_ajax_cart block enabled in order to potentially hijack the user's session. The issue is only known to affect sites that use some additional form of caching for authenticated users that shares Javascript settings values which is not a common case.
CVE: CVE-2012-2731
Versions affected
- uc_ajax_cart 6.x-2.x versions prior to 6.x-2.1.
Drupal core is not affected. If you do not use the contributed Ubercart AJAX Cart module, there is nothing you need to do.
Solution
Install the latest version:
- If you use the uc_ajax_cart module for Drupal 6.x, upgrade to uc_ajax_cart 6.x-2.1
Also see the Ubercart AJAX Cart project page.
