CVE-2017-8563

Estado: ModificadaAlta (8.1)—

Microsoft Windows 7 SP1, Windows Server 2008 SP2 y R2 SP1, Windows 8.1 y Windows RT 8.1, Windows Server 2012 y R2, Windows 10 Gold, 1511, 1607, 1703 y Windows Server 2016 permiten una vulnerabilidad de elevación de privilegios debido a que Kerberos vuelve a tener el protocolo de autenticación NT LAN Manager (NTLM) como el protocolo de autenticación por defecto. Esto también se conoce como "Windows 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).
