CVE-2025-54763Network attack vector

Authenticated command execution via undisclosed Web UI input

Published Oct 31, 2025 · Updated Oct 31, 2025

OS command injection in Century Systems FutureNet MA and IP-K firmware allows remote authenticated users to execute commands via the Web UI. The vendor and CNA identify the Web UI as the entry point but do not disclose the affected request handler, parameter, or missing neutralization operation. A valid Web UI login with high privileges is required; successful exploitation runs arbitrary commands on the appliance.
