  • Advisory ID: DRUPAL-SA-CONTRIB-2014-069
  • Project: LoginToboggan (third-party module)
  • Version: 7.x
  • Date: 2014-July-09
  • Security risk: Moderately critical
  • Exploitable from: Remote
  • Vulnerability: Cross Site Scripting, Access bypass

Description

This module enables you to customise the standard Drupal registration and login processes.

Cross Site Scripting

The module doesn't filter user-supplied information from the URL resulting in a reflected Cross Site Scripting (XSS) vulnerability.

Access Bypass

The module introduces a concept of a "pre-authorized role" which can have different permissions than the normal Drupal core authorized role. Logintoboggan usually removes permissions for a user if those permissions are in the "authorized user" role and not in the "pre-authorized role". The module failed to remove those permissions for users in a pre-authorized state on all "Page Not Found" (i.e. 404) pages.

This vulnerability is mitigated by the fact that a site must use the "pre-authorized role" feature and an attacker would only gain permissions available to authenticated users and would only gain them on 404 pages which do not show private information in a default Drupal installation.
