En el servicio de simulación, existe una forma posible de escribir registros de uso de permisos de una aplicación debido a que falta una verificación de permisos. Esto podría llevar a una escalada local de privilegios con permisos de ejecución de System necesarios.

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).
