* Advisory ID: DRUPAL-SA-CONTRIB-2015-169 * Project: Chat Room [1] (third-party module) * Version: 7.x * Date: 2015-December-02 * Security risk: 11/25 ( Moderately Critical) AC:Complex/A:None/CI:Some/II:None/E:Theoretical/TD:Default [2] * Vulnerability: Access bypass
-------- DESCRIPTION ---------------------------------------------------------
Chat Room enables site owners to integrate chats into nodes by adding the chat room field to them. The module relies on a websocket connection to send chat messages to the client.
The module doesn't sufficiently validate access before setting up the websocket. As a result, users may receive messages from chat rooms they don't have access to via the websocket.
-------- CVE IDENTIFIER(S) ISSUED --------------------------------------------
* /A CVE identifier [3] will be requested, and added upon issuance, in accordance with Drupal Security Team processes./
-------- VERSIONS AFFECTED ---------------------------------------------------
* Chat Room 7.x-2.x versions prior to 7.x-2.2.
Drupal core is not affected. If you do not use the contributed Chat Room [4] module, there is nothing you need to do.
-------- SOLUTION ------------------------------------------------------------
Install the latest version:
* If you use the Chat Room module for Drupal 7.x, upgrade to Chat Room 7.x-2.2 [5]
