Estado: AplazadaAlta (8.1)—

A vulnerability exists in EnOcean SmartServer IoT version 4.60.009 and prior, which would allow remote attackers, in the LON IP-852 management messages, to send specially crafted IP-852 messages resulting in arbitrary OS command execution on the device.

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 CVSS con AV:N/PR:N/UI:N indica acceso remoto sin privilegios ni interacción. CWE-77 (Improper Neutralization of Special Elements) y mensaje IP-852 manipulado sustentan T1190. La descripción menciona 'arbitrary OS command execution', confirmando T1059 como impacto.

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.
