* Advisory ID: DRUPAL-SA-CONTRIB-2012-049 * Project: ShareThis [1] (third-party module) * Version: 7.x * Date: 2012-March-28 * Security risk: Moderately critical [2] * Exploitable from: Remote * Vulnerability: Cross Site Scripting, Cross Site Request Forgery -------- DESCRIPTION --------------------------------------------------------- The ShareThis module allows you to display social networking tools to users. The administration forms of the module do not properly use the Form API allowing a malicious user to inject unexpected settings, allowing for cross-site scripting attacks (XSS). Additionally, the module had an incomplete feature for updating these settings outside of the Form API which was vulnerable to a cross site request forgery attack. This vulnerability is mitigated by the fact that an attacker must have a role with the permission "administer sharethis". -------- VERSIONS AFFECTED --------------------------------------------------- * ShareThis 7.x-2.x versions prior to 7.x-2.2. Drupal core is not affected. If you do not use the contributed ShareThis [3] module, there is nothing you need to do. -------- SOLUTION ------------------------------------------------------------ Install the latest version: * If you use the ShareThis module for Drupal 7.x, upgrade to ShareThis 7.x-2.3 [4] Also see the ShareThis [5] project page. -------- REPORTED BY --------------------------------------------------------- * Travis Tomka [6] -------- FIXED BY ------------------------------------------------------------ * Greg Knaddison [7] of the Drupal Security Team * Rob Loach [8], the module maintainer -------- COORDINATED BY ------------------------------------------------------ * Greg Knaddison [9] of the Drupal Security Team * Michael Hess [10] of the Drupal Security Team -------- CONTACT AND MORE INFORMATION ---------------------------------------- The Drupal security team can be reached at security at drupal.org or via the contact form at http://drupal.org/contact [11].
