Is this vulnerability remotely exploitable across the public internet?

Yes, if the OCPP WebSocket endpoint is exposed over the internet or any untrusted network without additional network-layer controls. Any party that can reach the endpoint and knows or discovers a station ID can attempt impersonation in the absence of proper authentication.

What level of access does an attacker need to exploit this issue?

The attacker needs only network connectivity to the OCPP WebSocket endpoint and knowledge or a guess of a valid charging station identifier. They do not need valid credentials, prior access to a charger, or insider knowledge beyond what can often be inferred or enumerated.

What is the safest general fix pattern for this type of vulnerability?

The most robust fix is to enforce strong, cryptographic authentication for every charger connection—such as mutual TLS with per-device certificates or secure tokens bound to each station identity—and to reject any connection that lacks valid, verifiable credentials. The backend should treat the station ID as an attribute authenticated by these credentials, not as a credential by itself.
