CVE-2025-15355Network attack vector

Unauthenticated browser script execution

Published Dec 30, 2025 · Updated Dec 30, 2025

Reflected XSS in NetVision Information ISOinsight allows remote attackers to execute JavaScript in a user's browser through phishing links. The published advisory does not identify the affected page or request parameter, leaving the exact reflection and missing output-encoding operation undisclosed. Exploitation requires an unauthenticated attacker to persuade a user to open a crafted link; the resulting script executes in the ISOinsight web origin and affects that browser session.
