Estado: AnalizadaAlta (7.8)—

Improper access control in Microsoft PC Manager allows an authorized attacker to bypass a security feature locally.

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 sin UI indica escalada local de privilegios (T1068). CWE-284 (improper access control) permite bypass de controles de seguridad, típicamente resultando en ejecución de código o elevación de privilegios en Microsoft PC Manager.

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.
