Estado: AnalizadaCrítica (9.8)—

Use after free in Windows Failover Cluster allows an unauthorized attacker to execute code over a network.

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.

CWE-416 (use-after-free) en Failover Cluster accesible remotamente sin autenticación (AV:N/PR:N) permite ejecución de código arbitrario con máximos privilegios. Vector CVSS crítico y acceso remoto directo caracterizan explotación directa de servicio expuesto (T1190), resultando en ejecución de coman

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.
