- Advisory ID: DRUPAL-SA-CONTRIB-2012-022
- Project: CDN (third-party module)
- Version: 6.x, 7.x
- Date: 2012-February-15
- Security risk: Critical
- Exploitable from: Remote
- Vulnerability: Access bypass
The CDN module provides easy Content Delivery Network integration for Drupal sites. It alters file URLs, so that files are downloaded from a CDN instead of your web server.
When running in Origin Pull mode together with the "Far Future expiration" option, the module contains a vulnerability that allows anyone to view the contents of any *.php file within the site, including settings.php.
This vulnerability is mitigated by the fact that the site owner must have enabled the "Far Future expiration" option, and must be using the latest version of the module.
- CDN version 6.x-2.2
- CDN version 7.x-2.2
Drupal core is not affected. If you do not use the contributed CDN module, there is nothing you need to do.
Install the latest version:
