CVE-2025-21183

Estado: AnalizadaAlta (7.4)—

Windows Resilient File System (ReFS) Deduplication Service Elevation of Privilege Vulnerability

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 sin UI:R indica escalada de privilegios local. CWE-415 (use-after-free) en ReFS Deduplication sugiere ejecución de código con privilegios elevados tras la explotación.

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.
