CVE-2019-1458

Estado: AnalizadaAlta (7.8)⚠ Explotación activa💥 Exploit

Hay una vulnerabilidad de elevación de privilegios en Windows cuando el componente Win32k no puede manejar apropiadamente los objetos en memoria, también se conoce como "Win32k Elevation of Privilege Vulnerability".

CVSS

Versión: 3.1
Vector: CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H
Puntuación base: 7.8

Probabilidad de explotación (EPSS)

Probabilidad de explotación en los próximos 30 días: 74%
Percentil entre todas las CVEs puntuadas: 99
Fecha de la puntuación: 8/10/2026

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).

CISA KEV — explotada activamente

Añadida al catálogo: 10/1/2022
Plazo de remediación: 10/7/2022
Uso conocido en ransomware: Known

💥 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.
