Estado: AnalizadaAlta (7.8)—

An issue in the TVicPort64.sys component of EnTech Taiwan TVicPort Product v4.0, File v5.2.1.0 allows attackers to escalate privileges via sending crafted IOCTL 0x80002008 requests.

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).

🎯 Técnicas ATT&CK

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

AV:L, PR:L, UI:N indica acceso local con privilegios limitados sin interacción. TVicPort64.sys permite escalada de privilegios mediante IOCTL crafted, alcanzando impacto C:H, I:H, A:H (administrador).

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.
