CVE-2025-29801

Estado: AnalizadaAlta (7.8)—

Incorrect default permissions in Microsoft AutoUpdate (MAU) 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.

AV:L + PR:L + acceso local sin UI:R → T1068. CWE-276 (permisos incorrectos) + escalada de privilegios confirman T1222. T1548 secundario por la elevación a privilegios superiores mencionada.

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.
