View online: https://www.drupal.org/node/2857014 * 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. -------- REPORTED BY --------------------------------------------------------- * Neil Drumm [7] of the Drupal Security Team -------- FIXED BY ------------------------------------------------------------ * Neil Drumm [8] of the Drupal Security Team -------- COORDINATED BY ------------------------------------------------------ * Micheal Hess [9] of the Drupal Security Team -------- CONTACT AND MORE INFORMATION ---------------------------------------- The Drupal security team can be reached at security at drupal.org or via the contact form at https://www.drupal.org/contact [10].
