CVE-2025-11303Public exploitNetwork attack vector

Authenticated command execution via mp parameter

Published Oct 5, 2025 · Updated Oct 5, 2025

Command injection in Belkin F9K1015 1.00.10 allows remote authenticated users to execute OS commands through the /goform/mp handler. The handler copies the POST command parameter into stack buffer s with sprintf without a length check, then passes the resulting string to system. Access to the web-management interface is required; injected commands run with that process's privileges and can alter device state or interrupt service.
