CVE-2024-43657Network attack vector

Root command execution via embedded firmware script

Published Jan 9, 2025 · Updated Mar 11, 2025

OS command injection in Iocharger firmware for AC model chargers before 2024120701 allows remote authenticated users to execute code as root. The firmware-update path accepts a crafted firmware file and executes an embedded shell script while action.exe processes the upload. Access to the web UI with any account, or interaction by a user who has such access, is required; successful exploitation grants full control of charger files and services.
