Executive Summary

This vulnerability is a Reflected Cross-Site Scripting (XSS) issue in Xibo CMS version 4.1.2. It occurs because the application does not properly validate user input in the 'Configuration Name' field of certain elements, such as the 'Clock' widget, within templates. An attacker can exploit this by creating a template, adding such an element, and then modifying the 'Configuration Name' field to inject malicious scripts that get reflected back to users.
