Vulnerability Overview

The Google Maps Easy WordPress plugin is vulnerable to Stored Cross-Site Scripting due to insufficient input validation and sanitization via several parameters found in the ~/modules/marker_groups/views/tpl/mgrEditMarkerGroup.php file which allowed attackers with administrative user access to inject arbitrary web scripts, in versions up to and including 1.9.33. This affects multi-site installations where unfiltered_html is disabled for administrators, and sites where unfiltered_html is disabled.

Technical Analysis

REMEDIATION: Update to version 1.10.1, or a newer patched version --- IDENTIFIER: CWE-79 (Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting')) The product does not neutralize or incorrectly neutralizes user-controllable input before it is placed in output that is used as a web page that is served to other users.
