View online: https://drupal.org/node/1828340 * Advisory ID: DRUPAL-SA-CONTRIB-2012-159 * Project: Password policy [1] (third-party module) * Version: 6.x, 7.x * Date: 2012-October-31 * Security risk: Moderately critical [2] * Exploitable from: Remote * Vulnerability: Information Disclosure -------- DESCRIPTION --------------------------------------------------------- This module provides a way to specify a certain level of password complexity (aka. "password hardening") for user passwords on a system by defining a password policy. The Password policy module allows administrators to request users to enter a new password that does not match any of the previous X passwords they have used (X is determined by the site configuration). If this feature is enabled, a malicious user with the capability to view another user's HTTP traffic can discover the hashed version of their password. This issue is more of a risk for Drupal 6 sites that use the default md5 password encryption. This issue only affects sites that use the module's "previous passwords" feature, and fail to encrypt their users' HTTP transactions with SSL/TLS. CVE: Requested -------- VERSIONS AFFECTED --------------------------------------------------- * Password policy 6.x-1.x versions prior to 6.x-1.5. * Password policy 7.x-1.x versions prior to 7.x-1.3. Drupal core is not affected. If you do not use the contributed Password policy [3] 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-1.5 [4] * If you use the Password policy module for Drupal 7.x, upgrade to Password policy 7.x-1.3 [5] Also see the Password policy [6] project page. -------- REPORTED BY --------------------------------------------------------- * Alexis Wilke [7] -------- FIXED BY ------------------------------------------------------------ * Mark Shropshire [8] -------- COORDINATED BY ------------------------------------------------------ * Greg Knaddison [9] of the Drupal Security Team * Michael Hess [10] of the Drupal Security Team * Damien Tournoud [11] 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 [12].
