CVE-2025-71318Public exploitNetwork attack vector

Unauthenticated UPS control via exposed administrative endpoints

Published Jun 5, 2026 · Updated Jun 5, 2026

Missing authentication in Riello UPS NetMan 204 version 0 allows remote attackers to read data and control UPS functions via HTTP. The embedded web interface serves administration.html, administration-commands.html, and configuration.html without checking credentials. Network access alone exposes LDAP settings and active-user details and permits shutdown, reboot, bypass switching, and battery tests.
