* 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.

-------- CVE IDENTIFIER(S) ISSUED --------------------------------------------

* /A CVE identifier [3] will be requested, and added upon issuance, in accordance with Drupal Security Team processes./

-------- VERSIONS AFFECTED ---------------------------------------------------

* RESTful Web Services 7.x-2.x versions prior to 7.x-2.6. * RESTful Web Services 7.x-1.x versions prior to 7.x-1.7.
