WebSocket endpoints lack proper authentication mechanisms, enabling attackers to impersonate charging stations. As a result, attackers can exploit this weakness to gain unauthorized access to sensitive data or perform unauthorized actions. Given that no authentication is required, this can lead to privilege escalation and potentially compromise the security of the entire system.
Monta states that their platform handles duplicate connection attempts per the OCPP specification, where a new authenticated connection supersedes an existing session for the same station ID.
