Open ISES Tickets Reflected Cross-Site Scripting Vulnerability in ics205a.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 file ics205a.php, where authenticated attackers can inject arbitrary JavaScript. This is achieved by sending an unsanitized value through the frm_add_str POST parameter, which is then inserted into a hidden input value attribute of an HTML form. The injected JavaScript executes in the browser of the victim when the response is displayed.

Impact

Exploitation of this vulnerability allows for reflected cross-site scripting, where injected scripts are executed in the context of the user's browser.

Reproduction

To reproduce this vulnerability, an authenticated user can send a POST request to a page that includes the frm_add_str parameter. This parameter should be populated with a JavaScript payload. When the response is rendered in the browser, the injected script will execute, demonstrating the cross-site scripting vulnerability.

Remediation

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