Entity Registration – Moderately Critical – Information Disclosure – SA-CONTRIB-2015-155

Leave a comment

Description

This module enables you to manage registrations for events.

The module doesn’t sufficiently protect information about who is registered to attend specific events when anonymous users are granted a permission that is commonly recommended when allowing anonymous registrations.

This vulnerability is mitigated by the fact that anonymous users must have the permission “Register other accounts.”

CVE identifier(s) issued

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

Versions affected

  • Entity Registration 7.x-1.x versions prior to 7.x-1.5.

Drupal core is not affected. If you do not use the contributed Entity Registration module, there is nothing you need to do.

Solution

Install the latest version:

Note on releases: the security bug was fixed in the 7.x-1.5 release, however that release included many other bug fixes and features. The 7.x-1.6 release is intended to fix a critical, non-security bug in the 7.x-1.5 release.

Update permissions configuration:

  • Remove the “Register other accounts” permission for anonymous users or other unprivileged roles
  • If needed, add the “Register Self” permission for anonymous users and other unprivileged roles

Also see the Entity Registration project page.
