CVE-2025-59817

Estado: AplazadaAlta (8.4)—

This vulnerability allows attackers to execute arbitrary commands on the underlying system. Because the web portal runs with root privileges, successful exploitation grants full control over the device, potentially compromising its availability, confidentiality, and integrity.

CVSS

Versión: 3.1
Vector: CVSS:3.1/AV:A/AC:L/PR:H/UI:N/S:C/C:H/I:H/A:H
Puntuación base: 8.4

Probabilidad de explotación (EPSS)

Probabilidad de explotación en los próximos 30 días: 0.25%
Percentil entre todas las CVEs puntuadas: 15
Fecha de la puntuación: 6/10/2026

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).
