Estado: AnalizadaAlta (8.8)⚠ Explotación activa💥 Exploit

Las versiones 10 y 11 de Microsoft Internet Explorer con JScript 9 permiten a atacantes la ejecución de código arbitrario o provocar denegación de servicio (corrupción de memoria) mediante sitios web manipulados, también conocida como 'Vulnerabilidad de corrupción de Memoria en JScript9'.

CVSS

Versión: 3.1
Vector: CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:H
Puntuación base: 8.8

Probabilidad de explotación (EPSS)

Probabilidad de explotación en los próximos 30 días: 53%
Percentil entre todas las CVEs puntuadas: 99
Fecha de la puntuación: 7/10/2026

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: 28/3/2022
Plazo de remediación: 18/4/2022
Uso conocido en ransomware: Unknown

💥 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.
