CVE-2017-20234

Estado: Pendiente de análisisCrítica (9.3)—

GarrettCom Magnum 6K and 10K managed switches contain an authentication bypass vulnerability that allows unauthenticated attackers to gain unauthorized access by exploiting a hardcoded string in the authentication mechanism. Attackers can bypass login controls to access administrative functions and sensitive switch configuration without valid credentials.

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:N/PR:N/UI:N indica vulnerabilidad de red sin autenticación previa. CWE-798 (hardcoded credentials) permite bypass de autenticación y acceso a funciones administrativas del switch.

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.
