• Advisory ID: DRUPAL-SA-CONTRIB-2016-063
• Project: High-performance JavaScript callback handler (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
• 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 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 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

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 project page.
