Executive Summary

[{'type': 'paragraph', 'content': "CVE-2025-40895 is a Stored HTML Injection vulnerability in the Sensor Map feature of Nozomi Networks' CMC versions prior to 25.6.0. It occurs because of improper validation of properties on connected Guardians. A malicious authenticated user with administrator privileges on a Guardian can inject arbitrary HTML tags by editing the Guardian's properties. When the Sensor Map functionality is enabled, these injected HTML elements may be rendered in the browsers of other CMC users interacting with the map."}, {'type': 'paragraph', 'content': 'Although this can enable phishing and open redirect attacks, full cross-site scripting (XSS) exploitation and direct information disclosure are prevented by existing input validation and Content Security Policy configurations.'}] [1]
