Open ISES Tickets Reflected Cross-Site Scripting Vulnerability in add_facnote.php

A reflected cross-site scripting vulnerability has been identified in Open ISES Tickets versions prior to 3.44.2. The issue resides in the add_facnote.php file, where authenticated attackers can inject arbitrary JavaScript. This is achieved by passing an unsanitized value through the ticket_id GET parameter, which is then directly inserted into a hidden input field's VALUE attribute. When the crafted URL is visited, the JavaScript payload executes in the victim's browser.

Impact

Exploitation of this vulnerability allows for reflected cross-site scripting, where an attacker can inject and execute malicious scripts in the context of the user's browser.

Reproduction

To reproduce this vulnerability, an authenticated user can send a request to add_facnote.php with a crafted ticket_id parameter that includes a JavaScript payload. The injected script will execute when the URL is accessed.

Remediation

Users are advised to upgrade to Open ISES Tickets version 3.44.2 or later, where this vulnerability has been patched.
