CVE-2024-30220

Arbitrary command execution via crafted adjacent-network request

Published Apr 15, 2024 · Updated Aug 27, 2025

Command injection in PLANEX MZK-MF300N and MZK-MF300HP2 routers allows remote attackers to execute arbitrary commands. A crafted request to an unspecified service on a certain port reaches command execution without authentication; public advisories do not identify the handler, parameter, or failed neutralization operation. The attacker must have adjacent-network access, and successful exploitation permits commands that can read or alter data and interrupt the router.
