CVE-2024-21945

Estado: AnalizadaAlta (7.3)—

Incorrect default permissions in the AMD RyzenTM Master monitoring SDK installation directory could allow an attacker to achieve privilege escalation potentially resulting in arbitrary code execution.

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.

UI:R (requiere interacción) + AV:L (acceso local) → T1203 (ejecución en cliente). Permisos incorrectos + escalada de privilegios + code execution → T1068 + T1059.

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.
