CVE-2024-28136Known exploitation

Root code execution via crafted Charger ID

Published May 14, 2024 · Updated Jan 24, 2025

Command injection in Phoenix Contact CHARX SEC-3xxx firmware 1.5.1 and earlier allows remote attackers to execute code as root. The OCPP Remote service passes the user-controlled Charger ID from a Get Diagnostics command into a system call without validating special characters. Exploitation requires an open OCPP management port and an attacker-controlled OCPP backend; successful commands run with root privileges.
