CVE-2024-21880Network attack vector

Authenticated OS command execution via URL parameter

Published Aug 10, 2024 · Updated Mar 11, 2025

OS command injection in Enphase Energy Envoy 4.x through 7.x allows remote authenticated users to execute arbitrary OS commands. An authenticated web endpoint passes its url parameter to an OS command without neutralizing command-control characters; its path and implementing function are undisclosed. Administrative access and network reachability to the gateway are required, and successful exploitation grants control of the appliance.
