CVE-2026-20965

Estado: AnalizadaAlta (7.5)—

Improper verification of cryptographic signature in Windows Admin Center 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 sin UI:N y acceso privilegiado (PR:H) indica escalada local. CWE-347 (verificación criptográfica impropia) sustenta manipulación de firmas (T1553.006); la consecuencia es elevación de privilegios (T1548).

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.
