CVE-2024-43522

Estado: AnalizadaAlta (7)—

Vulnerabilidad de elevación de privilegios de la autoridad de seguridad local (LSA) 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 PR:L sin UI:N indica escalada de privilegios local. CWE-122 (buffer overflow) en LSA permite ejecutar código con privilegios elevados y potencialmente asumir identidades.

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.
