FKIE_CVE-2026-27772

Vulnerability from fkie_nvd - Published: 2026-02-27 00:16 - Updated: 2026-02-27 14:06
Severity ?
9.4 (Critical) - CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:L
Summary
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.

Un atacante no autenticado puede conectarse al punto final WebSocket de OCPP utilizando un identificador de estaci\u00f3n de carga conocido o descubierto, luego emitir o recibir comandos OCPP como un cargador leg\u00edtimo. Dado que no se requiere autenticaci\u00f3n, esto puede llevar a escalada de privilegios, control no autorizado de la infraestructura de carga y corrupci\u00f3n de los datos de la red de carga reportados al backend."
