By Drupal Security Team on
  • Advisory ID: DRUPAL-SA-CONTRIB-2014-028
  • Project: Masquerade (third-party module)
  • Version: 6.x, 7.x
  • Date: 2014-March-05
  • Security risk: Highly critical
  • Exploitable from: Remote
  • Vulnerability: Access bypass

Description

This module allows a user with the right permissions to switch users.

When a user has been limited to only masquerading as certain users via the "Enter the users this user is able to masquerade as" user profile field, they can still masquerade as any user on the site by using the "Enter the username to masquerade as." autocomplete field in the masquerade block.

This vulnerability is mitigated by the fact that an attacker must have access to masquerade as another user.

CVE identifier(s) issued

  • A CVE identifier will be requested, and added upon issuance, in accordance with Drupal Security Team processes.
