The massive sending of ARP requests causes a denial of service on one board of the charger that allows control of the EV interfaces. Since the board must be operating correctly for the charger to also function correctly.

CVSS

Probabilidad de explotación (EPSS)

EPSS (Exploit Prediction Scoring System, de FIRST) estima la probabilidad de que una vulnerabilidad sea explotada en 30 días. Complementa a CVSS (impacto) y a CISA KEV (explotación confirmada).

🎯 Técnicas ATT&CK

Cómo se explota esta vulnerabilidad y qué consigue el atacante, en el lenguaje de MITRE ATT&CK.

Vector CVSS indica acceso remoto sin autenticación (AV:N/PR:N/UI:N). El ataque masivo de solicitudes ARP causa negación de servicio (CWE-400: Uncontrolled Resource Consumption). Explotación de servicio expuesto en tablero de cargador de vehículos eléctricos.

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.
