  * Advisory ID: DRUPAL-SA-CONTRIB-2012-085
  * Project: BrowserID (Mozilla Persona) [1] (third-party module)
  * Version: 7.x
  * Date: 2012-May-23
  * Security risk: Critical [2]
  * Exploitable from: Remote
  * Vulnerability: Cross Site Request Forgery (results in Privilege
    Escalation)

-------- DESCRIPTION  
---------------------------------------------------------

CVE: Requested
The BrowserID module provides integration with BrowserID (also known as
Mozilla Persona) -- a Mozilla project that lets users of your site quickly
and easily log in without needing to remember a password specific to your
site.

The module did not sufficiently validate requests for authentication to log
in, potentially allowing a Cross Site Request Forgery (CSRF) attack and
introducing the possibility that logging in to a malicious site with
BrowserID could give that site the ability to log in to other websites using
your BrowserID identity.

-------- VERSIONS AFFECTED  
---------------------------------------------------

  * BrowserID (Mozilla Persona) 7.x-1.x versions prior to 7.x-1.3.

Drupal core is not affected. If you do not use the contributed BrowserID
(Mozilla Persona) [3] module, there is nothing you need to do.

-------- SOLUTION  
------------------------------------------------------------

Install the latest version:

  * If you use the BrowserID module for Drupal 7.x, upgrade to BrowserID
    7.x-1.3 [4]

This version adds a dependency on the Session API [5] module. Make sure you
install Session API /before/ upgrading to BrowserID 7.x-1.3.

Also see the BrowserID (Mozilla Persona) [6] project page.
