CVE-2019-1170

Estado: ModificadaAlta (8.8)—💥 Exploit

existe una vulnerabilidad de elevación de privilegios cuando los puntos de reanálisis son creados mediante procesos dentro del sandbox que permiten el escape de mismo, también se conoce como "Windows NTFS Elevation of Privilege Vulnerability".

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).

💥 Exploits públicos

Hay código de explotación o plantillas de detección públicos. No es lo mismo que explotación activa confirmada (KEV), pero aumenta el riesgo: parchee con prioridad.
