Description

This module exploits a Remote PHP Code Execution vulnerability in the
Drupal RESTWS Module. Unauthenticated users can execute arbitrary code
under the context of the web server user.

RESTWS alters the default page callbacks for entities to provide
additional functionality. A vulnerability in this approach allows
an unauthenticated attacker to send specially crafted requests resulting
in arbitrary PHP execution. RESTWS 2.x prior to 2.6 and 1.x prior to 1.7
are affected by this issue.

This module was tested against RESTWS 2.5 with Drupal 7.5 installed on
Ubuntu Server.
