CVE-2018-0886

Estado: ModificadaAlta (7)—💥 Exploit

El protocolo CredSSP (Credential Security Support Provider) en Microsoft Windows Server 2008 SP2 y R2 SP1, Windows 7 SP1, Windows 8.1 y RT 8.1, Windows Server 2012 y R2, Windows 10 Gold, 1511, 1607, 1703 y 1709, Windows Server 2016 y Windows Server en su versión 1709 permite una vulnerabilidad de elevación de privilegios debido a la forma en la que CredSSP valida las peticiones durante el proceso de autenticación. Esto también se conoce como "CredSSP Remote Code Execution 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.

⚠️ Las pruebas de concepto de GitHub no están verificadas: algunas son falsas o contienen malware. No las ejecute nunca fuera de un laboratorio aislado.
