By Drupal Security Team on
  • Advisory ID: DRUPAL-SA-CONTRIB-2014-007
  • Project: Services (third-party module)
  • Version: 7.x
  • Date: 2014-January-29
  • Security risk: Highly critical
  • Exploitable from: Remote
  • Vulnerability: Multiple access bypass vulnerabilities

Description

This module enables you to expose an API to third party systems using REST, XML-RPC or other protocols.

The form API provides a method for developers to submit forms programmatically using the function drupal_form_submit(). During programmatic form submissions, all access checks are deliberately bypassed, and any form element may be submitted regardless of the current user's access level.

To facilitate this, a new, optional $form_state['programmed_bypass_access_check'] element has been added to the Drupal 7 form API. If this is provided and set to FALSE, drupal_form_submit() will perform the normal form access checks against the current user while submitting the form, rather than bypassing them.

Services relies heavily on programmatic form submission and therefore needs to use this new $form_state['programmed_bypass_access_check'] so that access control parameters and hooks are performed for untrusted users.
