• Project: Mass Contact (third-party module)
• Version: 6.x, 7.x
• Date: 2015-September-02
• Security risk: 13/25 ( Moderately Critical) AC:Basic/A:Admin/CI:Some/II:Some/E:Theoretical/TD:All
• Vulnerability: Cross Site Scripting

Description

This module allows anyone with permission to send a single message to multiple users of a site, using the site's roles and/or taxonomy functionality.

The module doesn't sufficiently sanitize the category labels when they are displayed.

This vulnerability is mitigated by the fact that an attacker must have a role with the permission "administer mass contact".
