By Drupal Security Team on
- Advisory ID: DRUPAL-SA-CONTRIB-2014-049
- Project: Organic groups (third-party module)
- Version: 7.x
- Date: 2014-May-07
- Security risk: Moderately critical
- Exploitable from: Remote
- Vulnerability: Access bypass
Description
Organic groups (OG) enables users to create and manage their own 'groups'. Each group can have subscribers, and maintains a group home page where subscribers communicate amongst themselves.
OG doesn't sufficiently check the permissions when a group member is pending or blocked status within the group and tries to access information in a site.
This vulnerability only affects sites using the "Organic groups access control" sub-module available within the Organic Groups package. It's further mitigated by the fact that an attacker must be a group member with pending or blocked status within the group.
CVE identifier(s) issued
- A CVE identifier will be requested, and added upon issuance, in accordance with Drupal Security Team processes.
Versions affected
- Organic Groups 7.x-2.x versions prior to 7.x-2.7.
Drupal core is not affected. If you do not use the contributed Organic groups module, there is nothing you need to do.
Solution
Install the latest version:
- If you use the Organic Groups module for Drupal 7.x, upgrade to Organic Groups 7.x-2.7
