CVE-2024-45493

Estado: AplazadaCrítica (9.8)—

An issue was discovered in MSA FieldServer Gateway 5.0.0 through 6.5.2 (Fixed in 7.0.0). The FieldServer Gateway has internal users, whose access is supposed to be restricted to login locally on the device. However, an attacker can bypass the check for this, which might allow them to authenticate with an internal user account from the network (if they know their password).

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.

Red remota sin autenticación (AV:N/PR:N) permite eludir restricción de acceso local de cuentas internas (CWE-862) y autenticarse remotamente, obteniendo acceso a cuenta válida.

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.
