CVE-2024-9404Network attack vector

Unauthenticated device crash via malformed moxa_cmd input

Published Dec 4, 2024 · Updated Aug 27, 2025

Improper input validation in Moxa moxa_cmd on affected switches and VPort 07-3 1.0 allows remote attackers to crash or reboot devices. The service accepts network input without sufficient type validation and processes malformed requests through a path that triggers a cold start or service failure. The service must be reachable over the network; resulting impact is limited to device or service interruption.
