Module Filter - Moderately critical - Cross site scripting - SA-CONTRIB-2019-042

Project: Module Filter
Version: 7.x-2.x-dev
Date: 2019-March-27
Security risk: 
Moderately critical 12/25 AC:Basic/A:Admin/CI:Some/II:Some/E:Theoretical/TD:Default
Vulnerability: Cross site scripting

Description: 

This module enables you to filter the list of modules on the admin modules
page, and organizes packages into vertical tabs.

The module doesn't sufficiently escape HTML under the scenario leading to a
Cross Site Scripting (XSS) vulnerability.

This vulnerability is mitigated by the fact that the attacker must have access
to input filtered html that will be included on the modules administration page
e.g. in a block (this configuration is not common). Further, the Module Filter
vertical tabs setting must be enabled.

Solution: 

Install the latest version:

  * If you use the Module Filter module for Drupal 7.x, upgrade to Module
    Filter 7.x-2.2

Also see the Module Filter project page.

Reported By: 

  * Yonatan Offek

Fixed By: 

  * greenSkin

Coordinated By: 

  * Greg Knaddison of the Drupal Security Team
