Description

This module exploits a PHP unserialize() vulnerability in Drupal RESTful
Web Services by sending a crafted request to the /node REST endpoint.

As per SA-CORE-2019-003, the initial remediation was to disable POST,
PATCH, and PUT, but Ambionics discovered that GET was also vulnerable
(albeit cached). Cached nodes can be exploited only once.

Drupal updated SA-CORE-2019-003 with PSA-2019-02-22 to notify users of
this alternate vector.
