Voting starts in March for the Drupal Association Board election.
- Advisory ID: DRUPAL-SA-CONTRIB-2013-003
- Project: RESTful Web Services (third-party module)
- Version: 7.x
- Date: 2013-January-16
- Security risk: Moderately critical
- Exploitable from: Remote
- Vulnerability: Cross Site Request Forgery
This module enables you to expose Drupal entities as RESTful web services. It provides a machine-readable interface to exchange resources in JSON, XML and RDF.
The module doesn't sufficiently verify POST requests thereby exposing a Cross Site Request Forgery vulnerability.
This vulnerability is mitigated by the fact that an attacker must trick an authenticated user onto a prepared page that leverages a weakness in certain browser plugins.
