CVE-2025-47161

Estado: ModificadaAlta (7.8)—

Improper access control in Microsoft Defender for Endpoint allows an authorized attacker to elevate privileges 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.

Acceso local (AV:L) sin interacción (UI:N) con privilegios (PR:L) en control de acceso impropio (CWE-284) permite escalada de privilegios. Attacker autorizado consigue elevación de derechos y posible acceso con permisos elevados.

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.
