A reboot of the charging controller can be triggered via Modbus TCP without authentication. Therefore, when the Modbus functionality is enabled by opening the port that CharxModbusServer is listening, an unauthenticated attacker can perform a Denial-of-Service attack.

Multiple vulnerabilities have been identified in the firmware of CHARX SEC-3xxx EV charging controllers, including the CHARX SEC-3000, SEC-3050, SEC-3100, and SEC-3150 models. The flaws could allow attackers to compromise the devices remotely, resulting in a complete loss of confidentiality, integrity, and availability.
