  * 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
