View online: https://www.drupal.org/node/2833790 * Advisory ID: DRUPAL-SA-CONTRIB-2016-063 * Project: High-performance JavaScript callback handler [1] (third-party module) * Version: 7.x * Date: 2016-December-07 * Security risk: 22/25 ( Highly Critical) AC:None/A:None/CI:All/II:All/E:Theoretical/TD:All [2] * Vulnerability: Cross Site Scripting, Access bypass, Cross Site Request Forgery, Open Redirect, Multiple vulnerabilities -------- DESCRIPTION --------------------------------------------------------- The High-performance JavaScript callback handler module is a light weight callback to bypass most, if not all, of Drupal's bootstrapping process to achieve improved performance. The module does not sufficiently check whether or not a callback is being properly accessed or filtering for potential XSS or CSRF exploits. -------- CVE IDENTIFIER(S) ISSUED -------------------------------------------- * /A CVE identifier [3] will be requested, and added upon issuance, in accordance with Drupal Security Team processes./ -------- VERSIONS AFFECTED --------------------------------------------------- * High-performance JavaScript callback handler (js) 7.x-1.x versions prior to 7.x-2.1. Drupal core is not affected. If you do not use the contributed High-performance JavaScript callback handler [4] module, there is nothing you need to do. -------- SOLUTION ------------------------------------------------------------ Install the latest version: * If you use the js module for Drupal 7.x, upgrade to js 7.x-2.1 [5] *Note:* this upgrade is not backwards compatible with 7.x-1.x. Existing contrib and custom module implementations of this API will either need to be upgraded, replaced or removed. Also see the High-performance JavaScript callback handler [6] project page. -------- REPORTED BY --------------------------------------------------------- * Anthony Leach (anthonyleach) [7] -------- FIXED BY ------------------------------------------------------------ * Mark Carver (markcarver) [8] - module maintainer -------- COORDINATED BY ------------------------------------------------------ * Michael 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].
