CVE-2019-0555

Estado: ModificadaAlta (7.8)—💥 Exploit

Existe una vulnerabilidad de elevación de privilegios en la clase Microsoft XmlDocument que podría permitir a un atacante escapar del sandbox AppContainer en el navegador. Esto también se conoce como "Microsoft XmlDocument Elevation of Privilege Vulnerability". Esto afecta a Windows Server 2012 R2, Windows RT 8.1, Windows Server 2012, Windows Server 2019, Windows Server 2016, Windows 8.1, Windows 10, Windows 10 Servers.

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.
