CVE-2026-9854

Estado: AnalizadaAlta (8.5)—

A vulnerability exists in SYS600 RBAC mechanism where users having access to the engineering tools could elevate their privileges to administrator level on the underlying Windows host, granting themselves full control over the host machine.

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.

Vector AV:L/PR:L sin UI permite escalada local de privilegios. El atacante con acceso a ingeniería obtiene privilegios de administrador en Windows (T1548) y control de cuenta de sistema (T1078.001).

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.
