Description
Open ISES Tickets before 3.44.2 contains a reflected cross-site scripting vulnerability in add_facnote.php that allows authenticated attackers to inject arbitrary JavaScript by passing an unsanitized value through the ticket_id GET parameter directly into a hidden input field VALUE attribute. Attackers can craft a malicious URL containing a JavaScript payload in the ticket_id parameter that executes in the victim's browser when the URL is visited.

AI Analysis

Impact

Open ISES Tickets versions before 3.44.2 contain an unsanitized ticket_id parameter that is reflected into a hidden input field, enabling an attacker to inject and execute arbitrary JavaScript in the victim’s browser when a crafted URL is visited.

Affected Systems

The affected system is the openises:tickets product, all releases prior to version 3.44.2.

Risk and Exploitability

The CVSS score of 5.1 indicates moderate risk; the vulnerability requires authenticated access and a user to click a malicious link, yet it can lead to phishing, session hijacking or data theft. With no EPSS data and absence from the KEV catalog, exploitation remains uncertain, but the lack of input sanitization suggests it could be abused if an attacker obtains user credentials or tricks users into visiting the URL.

Remediation

No vendor fix or workaround currently provided.

OpenCVE Recommended Actions

  • Update to openises:tickets v3.44.2 or later to eliminate the unsanitized ticket_id parameter.
  • Ensure that only trusted users can access add_facnote.php and that the ticket_id value is properly validated and escaped before rendering in the page.
  • Deploy a web application firewall rule that blocks reflected XSS attempts on the ticket_id input and monitor logs for suspicious ticket_id patterns.
