CVE-2019-0555
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
- Versión: 3.0
- Vector: CVSS:3.0/AV:L/AC:H/PR:L/UI:N/S:C/C:H/I:H/A:H
- Puntuación base: 7.8
Probabilidad de explotación (EPSS)
- Probabilidad de explotación en los próximos 30 días: 2.67%
- Percentil entre todas las CVEs puntuadas: 85
- Fecha de la puntuación: 9/10/2026
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.
- Publicado en Exploit-DB · Microsoft Windows 10 - XmlDocument Insecure Sharing Privilege Escalation (16/1/2019)
- Prueba de concepto en GitHub (no verificada) · Lista de pruebas de concepto en GitHub
⚠️ Las pruebas de concepto de GitHub no están verificadas: algunas son falsas o contienen malware. No las ejecute nunca fuera de un laboratorio aislado.
