[IT-SecNots] [Security-news] SA-CONTRIB-2012-007 - Password Policy - Multiple vulnerabilities

[security-news AT drupal.org]

  * 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."
