CVE-2018-0749

Estado: ModificadaAlta (7.8)—💥 Exploit

El servidor SMB (Server Message Block) de Microsoft en Windows 7 SP1, Windows 8.1 y RT 8.1, Windows Server 2008 SP2 and R2 SP1, Windows Server 2012 y R2, Windows 10 Gold 1511, 1607, 1709 y 1709, Windows Server 2016 y Windows Server en su versión 1709 permite una vulnerabilidad de elevación de privilegios por la manera en la que el servidor SMB gestiona archivos especialmente manipulados. Esta vulnerabilidad 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).

💥 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.
