* Advisory ID: DRUPAL-SA-CONTRIB-2016-040 * Project: RESTful Web Services [1] (third-party module) * Version: 7.x * Date: 2016-July-13 * Security risk: 22/25 ( Highly Critical) AC:None/A:None/CI:All/II:All/E:Theoretical/TD:All [2] * Vulnerability: Arbitrary PHP code execution
-------- DESCRIPTION ---------------------------------------------------------
This module enables you to expose Drupal entities as RESTful web services.
RESTWS alters the default page callbacks for entities to provide additional functionality.
A vulnerability in this approach allows an attacker to send specially crafted requests resulting in arbitrary PHP execution.
There are no mitigating factors. This vulnerability can be exploited by anonymous users.
