- Advisory ID: DRUPAL-SA-CONTRIB-2014-015
- Project: FileField (third-party module)
- Version: 6.x
- Date: 2014-02-12
- Security risk: Moderately critical
- Exploitable from: Remote
- Vulnerability: Access bypass
FileField module allows users to upload files with in conjunction with the Content Construction Kit (CCK) module in Drupal 6.
The module doesn't sufficiently check permissions on revisions when determining if a user should have access to a particular file attached to that revision. A user could gain access to private files attached to revisions when they don't have access to the corresponding revision.
This vulnerability is mitigated by the fact that an attacker must have access to upload files through FileField module while creating content, and the site must be using a non-core workflow module that allows users to create unpublished revisions of content.
