Views Bulk Operations – Moderately critical – Access Bypass – SA-CONTRIB-2015-131

Leave a comment

Description

The Views Bulk Operations module enables you to add bulk operations to administration views, executing actions on multiple selected rows.

The module doesn’t sufficiently guard user entities against unauthorized modification. If a user has access to a user account listing view with VBO enabled (such as admin/people when the administration_views module is used), they will be able to edit their own account and give themselves a higher role (such as “administrator”) even if they don’t have the “‘administer users'” permission.

This vulnerability is mitigated by the fact that an attacker must have access to such a user listing page and that the bulk operation for changing Roles is enabled.

CVE identifier(s) issued

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

Versions affected

  • Views Bulk Operations 7.x-3.x versions prior to 7.x-3.3.

Solution
