CVE-2026-18901Public exploitNetwork attack vector

Root command execution via exposed service.add RPC

Published Aug 5, 2026 · Updated Aug 5, 2026

Exposed dangerous function in H3C Magic NX15 Wireless Router V100R017 allows remote authenticated users to execute commands as root. The authenticated /api/esps bridge forwards service.add parameters, including an attacker-controlled command array, to the privileged procd service manager. An administrator web session is required; procd starts the supplied service command with UID 0, granting full control of the router.
