WebSocket endpoints lack proper authentication mechanisms, enabling attackers to perform unauthorized station impersonation and manipulate data sent to the backend. An unauthenticated attacker can connect to the OCPP WebSocket endpoint using a known or discovered charging station identifier, then issue or receive OCPP commands as a legitimate charger. Given that no authentication is required, this can lead to privilege escalation, unauthorized control of charging infrastructure, and corruption of charging network data reported to the backend.

Fixes

Solution

IGL-Technologies has updated eParking's OCPP servers to reduce the risks posed by the vulnerability. These updates implemented the following security controls: 1-Enforce modern security profiles and stronger authentication. 2-Device level whitelisting was implemented to ensure authorized devices connect. 3-Rate limiting controls prevent excessive requests and reduces denial-of-service attacks. 4-Enhanced automated monitoring and alerting to detection abnormal network activity. Devices using the encrypted deployment of eParking's OCPP servers or IGL-Technologies proprietary eTolppa protocol are not impacted by these vulnerabilities.


Workaround

No workaround given by the vendor.
