CVE-2025-53520

Estado: AplazadaAlta (8.6)—

The affected product allows firmware updates to be downloaded from EG4's website, transferred via USB dongles, or installed through EG4's Monitoring Center (remote, cloud-connected interface) or via a serial connection, and can install these files without integrity checks. The TTComp archive format used for the firmware is unencrypted and can be unpacked and altered without detection.

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.

UI:R y descarga de firmware sin validación de integridad permiten ejecución en cliente. T1195.002 por manipulación de paquete de actualización; T1059 por ejecución de código arbitrario tras instalar firmware modificado.

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.
