* Advisory ID: DRUPAL-SA-CONTRIB-2012-007 * Project: Password policy [1] (third-party module) * Version: 6.x * Date: 2012-January-11 * Security risk: Moderately critical [2] * Exploitable from: Remote * Vulnerability: Cross Site Scripting, Cross Site Request Forgery -------- DESCRIPTION --------------------------------------------------------- This module enables you to specify a certain level of password complexity (aka. "password hardening") for user passwords on a system by defining a policy. .... Cross Site Request Forgery (CSRF) Unblocking a user does not require sufficient confirmation by administrative users and can be exploited with a specially crafted URL. .... Cross Site Scripting (XSS) The module doesn't sufficiently sanitize the name of password policies. This vulnerability is mitigated by the fact that an attacker must have a role with the permission "administer policies". This issue also affects the 7.x branch which is only in beta release. Users of non-stable releases are encouraged to upgrade frequently as those releases are not covered by the Drupal Security Team policy [3]. -------- VERSIONS AFFECTED --------------------------------------------------- * Password Policy 6.x-1.x versions prior to 6.x-1.4. Drupal core is not affected. If you do not use the contributed Password policy [4] module, there is nothing you need to do. -------- SOLUTION ------------------------------------------------------------ Install the latest version: * If you use the Password Policy module for Drupal 6.x, upgrade to Password Policy 6.x-1.4 [5]. Clear the site's cache: visit Administer > Site Configuration > Performance and click "Clear cached data." See also the Password policy [6] project page. -------- REPORTED BY --------------------------------------------------------- * Greg Knaddison [7] of the Drupal Security Team -------- FIXED BY ------------------------------------------------------------ * Erik Webb [8] the module co-maintainer -------- COORDINATED BY ------------------------------------------------------ * Greg Knaddison [9] 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 [10].
