Executive Summary

CVE-2026-48214 is a reflected cross-site scripting (XSS) vulnerability found in Open ISES Tickets versions before 3.44.2, specifically in the add_nm.php file.

Authenticated attackers can exploit this vulnerability by injecting arbitrary JavaScript code through the ticket_id POST parameter, which is not properly sanitized.

The injected JavaScript is directly inserted into an HTML form input value attribute and an inline JavaScript string literal, causing the malicious code to execute in the victim's browser when the response is rendered.

Impact Analysis

This vulnerability allows attackers to execute arbitrary JavaScript in the context of a victim's browser, which can lead to several impacts.

• The attacker can steal sensitive information such as session cookies or authentication tokens.
• It can enable attackers to perform actions on behalf of the victim within the application.
• It may lead to further attacks like phishing or spreading malware by manipulating the content displayed to the user.

Detection Guidance

This vulnerability can be detected by monitoring HTTP POST requests to the add_nm.php endpoint, specifically looking for the ticket_id parameter containing suspicious or malicious JavaScript payloads.

A practical approach is to capture and inspect POST requests to add_nm.php for unsanitized input in the ticket_id parameter that might be reflected in the response.

Example commands to detect potential exploitation attempts include using curl or tools like Burp Suite or OWASP ZAP to send crafted POST requests and observe the response for reflected scripts.

• curl -X POST -d "ticket_id=<script>alert(1)</script>" https://your-target-domain/add_nm.php -v
• Use a web proxy tool (e.g., Burp Suite) to intercept and modify ticket_id POST parameters to include JavaScript payloads and check if they are reflected unsanitized in the response.

Mitigation Strategies

The immediate mitigation step is to upgrade Open ISES Tickets to version 3.44.2 or later, where this reflected XSS vulnerability has been fixed.

Until the upgrade can be applied, restrict access to the affected add_nm.php endpoint to trusted authenticated users only, and consider implementing web application firewall (WAF) rules to block suspicious payloads in the ticket_id parameter.
