* Advisory ID: DRUPAL-SA-CONTRIB-2009-102 * Project: PHPList Inegration Module (third-party module) * Version: 5.x, 6.x * Date: 2009-November-18 * Security risk: Less Critical * Exploitable from: Remote * Vulnerability: Cross site request forgery -------- DESCRIPTION --------------------------------------------------------- The PHPList module provides a basic level of integration between Drupal and the PHPList mailing list application. 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 a site where they are authenticated. The links for subscribing and un-subscribing to and from mailing lists in "My Account" do not follow the standard Forms API submission model and are therefore not protected against this type of attack. A CSRF attack may result in unintentional subscription or un-subscription of site users to PHPList mailing lists. -------- VERSIONS AFFECTED --------------------------------------------------- * PHPList Integration Module for Drupal 5 before 5.x-1.2 * PHPList Integration Module for Drupal 6 before 6.x-1.1 Drupal core is not affected. If you do not use the contributed PHPList Integration module, there is nothing you need to do. -------- SOLUTION ------------------------------------------------------------ Install the latest version: If you use Drupal 5.x upgrade to PHPList Integration Module 5.x-1.2 [1]. If you use Drupal 6.x upgrade to PHPList Integration Module 6.x-1.1 [2]. See also the PHPList Integration Module [3] project page. -------- REPORTED BY --------------------------------------------------------- Peter Wolanin [4] of the Drupal Security Team -------- FIXED BY ------------------------------------------------------------ Paul Beaney [5] the module maintainer. -------- CONTACT ------------------------------------------------------------- The security contact for Drupal can be reached at security at drupal.org or via the form at http://drupal.org/contact.
