Estado: ModificadaMedia (4.6)—💥 Exploit

Los controladores de dispositivo de (a) NAVENG (NAVENG.SYS) y (b) NAVEX15 (NAVEX15.SYS) 20061.3.0.12 y posteriores, utilizados en Symantec AntiVirus y en productos de seguridad, permiten a usuarios locales escalar privilegios sobreescribiendo direcciones críticas del sistema utilizando un Irp (paquete de petición de Entrada/salida) creado artesanalmente para las funciones IOCTL (1) 0x222AD3, (2) 0x222AD7, y (3) 0x222ADB.

CVSS

Versión: 2.0
Vector: AV:L/AC:L/Au:N/C:P/I:P/A:P
Puntuación base: 4.6

Probabilidad de explotación (EPSS)

Probabilidad de explotación en los próximos 30 días: 1.75%
Percentil entre todas las CVEs puntuadas: 77
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).

💥 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.
