CVE-2018-0821

Estado: ModificadaAlta (7)—💥 Exploit

AppContainer en Windows 10 Gold, 1511, 1607, 1703 y 1709, Windows Server 2016 y Windows Server versión 1709 permite una vulnerabilidad de elevación de privilegios debido a la forma en la que se gestionan las suplantaciones restringidas. Esto también se conoce como "Windows AppContainer 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.
