CVE-2026-29796

Estado: AnalizadaCrítica (9.3)—

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.

Vector AV:N/PR:N/UI:N (red sin autenticación) indica T1190. CWE-306 (falta de autenticación) permite asumir identidad de estación (T1078). Manipulación de datos OCPP y control no autorizado confirma T1565.001 y T1098.001.

Inferido por nuestro agente de análisis a partir de la descripción oficial, el vector CVSS y la CWE, y comprobado por un supervisor. Puede contener errores.
