CVE-2019-0709

Estado: ModificadaAlta (7.6)—💥 PoC

Existe una vulnerabilidad en la ejecución de un código remoto cuando Windows Hyper-V en un servidor falla para validara correctamente entradas desde un usuario autorizado en un sistema operativo invitado, conocido como wíndows Hyper-V Remote Code Execution Vulnerability'. Este CVE ID es único desde CVE-2019-0620, CVE-2019-0722.

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.
