CVE-2026-27767
CriticalSummary
Punkty końcowe WebSocket nie mają odpowiednich mechanizmów uwierzytelniania, co umożliwia atakującym podszywanie się pod stacje i manipulowanie danymi wysyłanymi do zaplecza. Atakujący bez uwierzytelnienia może połączyć się z punktem końcowym OCPP WebSocket, używając znanego identyfikatora stacji ładowania, a następnie wydawać lub odbierać polecenia OCPP jako legalna ładowarka.
Risk Assessment
Brak uwierzytelnienia może prowadzić do eskalacji uprawnień, nieautoryzowanej kontroli infrastruktury ładowania oraz zniekształcenia danych sieci ładowania raportowanych do zaplecza, co stwarza poważne zagrożenie dla bezpieczeństwa organizacji.
Recommendation
Zaleca się wdrożenie odpowiednich mechanizmów uwierzytelniania dla punktów końcowych WebSocket, aby zapobiec nieautoryzowanemu dostępowi i manipulacji danymi.

Original NVD description (English source)
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.
