By Drupal Security Team on
  • Advisory ID: DRUPAL-SA-CONTRIB-2013-064
  • Project: Mozilla Persona (third-party module)
  • Version: 7.x
  • Date: 2013-August-07
  • Security risk: Less critical
  • Exploitable from: Remote
  • Vulnerability: Cross Site Request Forgery

Description

This module enables users to sign into a Drupal website using Mozilla Persona.

The module uses a security token to ensure that a sign-in request is made from a web page that is participating in the current session. It was possible for a security token that was not of type "string" to be accepted as correct regardless of it's value, thereby bypassing the protection against cross site request forgery.

This vulnerability is mitigated by the fact that an attacker can only cause a victim to become signed in to an account that the attacker already has the ability to sign in to.
