CVE-2020-9211

Estado: AnalizadaAlta (7.2)—

There is an out-of-bound read and write vulnerability in Huawei smartphone. A module dose not verify the input sufficiently. Attackers can exploit this vulnerability by modifying some configuration to cause out-of-bound read and write, causing denial of service. (Vulnerability ID: HWPSIRT-2020-05103)

This vulnerability has been assigned a Common Vulnerabilities and Exposures (CVE) ID: CVE-2020-9211.

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.

Vector AV:N/AC:L/PR:H: acceso remoto con privilegios, requiere servicios remotos. Out-of-bound read/write causa DoS; potencial escalada de privilegios en memoria del dispositivo.

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.
