* Advisory ID: DRUPAL-SA-CONTRIB-2015-162 * Project: Login Disable [1] (third-party module) * Version: 6.x, 7.x * Date: 2015-November-04 * Security risk: 12/25 ( Moderately Critical) AC:Basic/A:User/CI:Some/II:Some/E:Theoretical/TD:Uncommon [2] * Vulnerability: Access bypass
-------- DESCRIPTION ---------------------------------------------------------
This module enables you to prevent existing users from logging in to your Drupal site unless they know the secret key to add to the end of the ?q=user login form page.
The Login Disable module doesn't support other contributed user authentication modules like CAS or URL Login. When combined with those modules, the protection preventing a user from logging in does not work.
This vulnerability is mitigated by the fact that an attacker must already have a user account to log in. This bug therefore allows users to log in even if they do not have permission to login.
-------- CVE IDENTIFIER(S) ISSUED --------------------------------------------
* /A CVE identifier [3] will be requested, and added upon issuance, in accordance with Drupal Security Team processes./
-------- VERSIONS AFFECTED ---------------------------------------------------
* Login Disable 6.x-1.x versions prior to 6.x-1.1. * Login Disable 7.x-1.x versions prior to 7.x-1.2.
Drupal core is not affected. If you do not use the contributed Login Disable [4] module, there is nothing you need to do.

* If you use the Login Disable module for Drupal 6.x, upgrade to Login Disable 6.x-1.1 [5] * If you use the Login Disable module for Drupal 7.x, upgrade to Login Disable 7.x-1.2 [6]
