CVE-2026-73174

Estado: Pendiente de análisisAlta (8.7)—

Nozomi Networks Labs identified a CWE-319: Cleartext Transmission of Sensitive Information vulnerability in the edgserver management protocol of Advantech EKI-1242EIMS in firmware version V1.06.01 that allows a network-adjacent passive observer to intercept management traffic and recover sensitive device identity and network metadata in cleartext.

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.

CWE-319 permite intercetar tráfico en claro de gestión (AV:A). El atacante adyacente a la red obtiene metadatos de identidad y configuración del dispositivo (T1005, T1552.001).

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.
