  * Advisory ID: DRUPAL-SA-CONTRIB-2017-024
  * Project: RESTful Web Services [1]     (third-party module)
  * Version: 7.x
  * Date: 2017-March-01
  * Security risk: 12/25 ( Moderately Critical)
    AC:Basic/A:None/CI:Some/II:None/E:Theoretical/TD:Default [2]
  * Vulnerability: Information Disclosure

-------- DESCRIPTION
---------------------------------------------------------

RestWS makes Drupal Entity data available in a REST API.

The module doesn’t sufficiently check for access to properties when
filtering queries.

This vulnerability is mitigated by the fact that an attacker must have a role
that allows them to access an entity type with access-controlled properties.
And the attacker can only query on the property equalling a value supplied by
the attacker.


-------- CVE IDENTIFIER(S) ISSUED
--------------------------------------------

  * /A CVE identifier [3] will be requested, and added upon issuance, in
    accordance with Drupal Security Team processes./

-------- VERSIONS AFFECTED
---------------------------------------------------

  * restws 7.x-2.x versions prior to 7.x-2.7.

Drupal core is not affected. If you do not use the contributed RESTful Web
Services [4] module, there is nothing you need to do.

-------- SOLUTION
------------------------------------------------------------

Install the latest version:

  * If you use the restws 2.x module for Drupal 7.x, upgrade to restws 
7.x-2.7
    [5]

Also see the RESTful Web Services [6] project page.
