CVE-2019-1132

Estado: AnalizadaAlta (7.8)⚠ Explotación activa💥 Exploit

Existe una vulnerabilidad de elevación de privilegios en Windows cuando el componente Win32k no maneja apropiadamente los objetos en la memoria, también se conoce como "Win32k 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).

CISA KEV — explotada activamente

💥 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.

🎯 Técnicas ATT&CK

Cómo se explota esta vulnerabilidad y qué consigue el atacante, en el lenguaje de MITRE ATT&CK.

Win32k fallo en manejo de objetos en memoria con AV:L/PR:L permite escalada de privilegios local. Acceso a ejecución de comandos y procesos con permisos elevados.

Inferido por nuestro agente de análisis a partir de la descripción oficial, el vector CVSS y la CWE, y comprobado por un supervisor. Puede contener errores.
