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

A reflected cross-site scripting vulnerability has been identified in Open ISES Tickets versions prior to 3.44.2. The issue resides in delete_module.php, where authenticated attackers can inject arbitrary JavaScript. This is achieved by sending an unsanitized value through several POST parameters (module_choice, flag, confirmation), which is then directly inserted into the rendered HTML content and form action attributes. As a result, attackers can execute JavaScript payloads in the context of the victim's browser 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 session.

Reproduction

To reproduce this vulnerability, an authenticated user can send a POST request to delete_module.php with malicious JavaScript embedded in the module_choice, flag, and confirmation parameters. The injected script will be executed when the response is rendered in the browser.

Remediation

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