CVE-2024-43527

Estado: AnalizadaAlta (7.8)—

Vulnerabilidad de elevación de privilegios en el kernel de Windows

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 indica acceso local sin interacción, vector típico de escalada de privilegios (T1068). CWE-122 (buffer overflow) en kernel permite ejecución de código (T1059) con máximos privilegios, acceso a datos sensibles (T1005) y manipulación de cuentas del sistema (T1078).

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.
