By Drupal Security Team on
  • Advisory ID: DRUPAL-SA-CONTRIB-2012-159
  • Project: Password policy (third-party module)
  • Version: 6.x, 7.x
  • Date: 2012-October-31
  • Security risk: Moderately critical
  • 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: CVE-2012-5552

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 module, there is nothing you need to do.
