SA-CONTRIB-2014-071 - FileField - Access bypass

The FileField module enables you to define and use fields that contain files.

The module doesn’t sufficiently check permission to view the attached file when attaching a file that was previously uploaded. This could allow attackers to gain access to private files.

This vulnerability is mitigated by the fact that the attacker must have permission to create or edit content with a file field.

CVE identifier(s) issued

• CVE-2014-9156

Versions affected

• FileField 6.x-3.x versions prior to 6.x-3.13.

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

Solution

• If you use the FileField module for Drupal 6.x, upgrade to Filefield 6.x-3.13, and also update to Drupal core 6.32 (see SA-CORE-2014-003).
