   * 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./

---------------------------------------------------

   * 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.
