CVE-2020-36979

Estado: AplazadaAlta (8.5)—

Atheros Coex Service Application 8.0.0.255 contains an unquoted service path vulnerability in its Windows service configuration. Attackers can exploit the unquoted path by placing malicious executables in the service path to gain elevated system privileges during service startup.

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:L/PR:L sin UI indica acceso local con privilegios de usuario. CWE-428 (unquoted service path) permite ejecución de código en contexto de servicio (SYSTEM) durante startup, escalando privilegios. El atacante ejecuta comandos maliciosos con permisos elevados.

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.
