CVE-2020-9222

Estado: AnalizadaAlta (7.8)—

There is a privilege escalation vulnerability in Huawei FusionCompute product. Due to insufficient verification on specific files that need to be deserialized, local attackers can exploit this vulnerability to elevate permissions. (Vulnerability ID: HWPSIRT-2020-05241)

This vulnerability has been assigned a Common Vulnerabilities and Exposures (CVE) ID: CVE-2020-9222.

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 interacción indica escalada de privilegios. La desserialización insegura en ficheros locales permite que atacantes con acceso local eleven permisos a niveles superiores, confirmado por CWE-269 y CVSS con C:H I:H A:H.

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.
