Technical details

An OS command injection vulnerability (CWE-78) exists in the firmware of Phoenix Contact CHARX SEC-3xxx charging controllers. The flaw is reachable by an unauthenticated remote attacker who has gained control over the Open Charge Point Protocol (OCPP) backend or can bypass the firewall to reach the service. Successful exploitation allows the execution of arbitrary commands as the limited user 'charx-oa'. This can result in a loss of availability (interruption of charging) and partial loss of confidentiality and integrity. The vulnerability is addressed in firmware version 1.9.1.
