* Advisory ID: DRUPAL-SA-CONTRIB-2014-045 * Project: Drupal Commons [1] (third-party module) * Version: 7.x * Date: 2014-April-23 * Security risk: Moderately critical [2] * Exploitable from: Remote * Vulnerability: Access bypass
-------- DESCRIPTION ---------------------------------------------------------
This SA contains two patches against Drupal Commons
.... Views Bulk Operations Access Bypass
Drupal commons comes with a view to moderate reported content, which is intended for authenticated users to view which content has been reported. Since it has hard coded VBO operations within the view, and Drupal Commons doesn't come with the VBO 'access_permissions' submodule enabled, all views bulk operations can be performed by anyone with access to the view. In its default setting, this allows users to delete content from other users and potentially ban other users from the site.
.... Anonymous Users can view Wiki revisions regardless of group privacy
Commons allows users of a group to edit a wiki created by anyone, regardless of edit permissions. It is supposed to refer back to the group permissions when creating this edit permission. However, the revisions permission hook allows anyone (anonymous or authenticated) to view revisions and diffs between revisions. This can potentially leak hidden data from groups a user does not otherwise have access to.
