View online: https://www.drupal.org/node/2782027 * Advisory ID: DRUPAL-SA-CONTRIB-2016-043 * Project: Piwik Web Analytics [1] (third-party module) * Version: 7.x, 8.x * Date: 2016-August-10 * Security risk: 13/25 ( Moderately Critical) AC:None/A:Admin/CI:Some/II:Some/E:Theoretical/TD:Uncommon [2] * Vulnerability: Cross Site Scripting -------- DESCRIPTION --------------------------------------------------------- This module enables you to add integration with Piwik statistics service. The module allows admin users to enter custom JavaScript snippets to add advanced tracking functionality. The permission required to enter this JavaScript was not marked as restricted. This vulnerability is mitigated by the fact that an attacker must have a role with the permission "Administer Piwik". For greater flexibility a new feature has been added to the module to implement the new permission "Add JavaScript snippets" that can be assigned to users who are allowed to add JS code snippets into your web site. If you have granted the Administer Google Analytics to non trusted users, please check your settings to make sure all javascript entered is valid. -------- CVE IDENTIFIER(S) ISSUED -------------------------------------------- * /A CVE identifier [3] will be requested, and added upon issuance, in accordance with Drupal Security Team processes./ -------- VERSIONS AFFECTED --------------------------------------------------- * Piwik 7.x-2.x versions prior to 7.x-2.9. * Piwik 8.x-2.x versions prior to 8.x-1.1.
