|
|
This module exploits the Drupal RESTWS module vulnerability.
|
|
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
|
|
|
|
This module was tested against RESTWS 7.x with Drupal 7.5
|
|
installation on Ubuntu server.
