Open ISES Tickets Reflected Cross-Site Scripting Vulnerability

A reflected cross-site scripting vulnerability has been identified in Open ISES Tickets versions prior to 3.44.2. The issue resides in landb.php, where authenticated attackers can inject arbitrary JavaScript. This is achieved by sending an unsanitized value through the _type POST parameter, which is then inserted into a hidden input value attribute of an HTML form. When the response is rendered, the injected JavaScript 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 session.

Reproduction

To reproduce this vulnerability, an authenticated user can send a POST request to landb.php with a payload containing JavaScript injected into the _type parameter. The unsanitized value will be reflected in a hidden input field, and the script will execute when the response is loaded 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.
