CVE-2025-43873

Estado: AplazadaAlta (8.7)—

Successful exploitation of these vulnerabilities could allow an attacker to modify firmware and gain full access to 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.

AV:N con PR:L sugiere servicio remoto con privilegios. CWE-78 (inyección OS) + 'modify firmware' y 'full access' indican ejecución de comandos tras acceso autenticado a servicio remoto.

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.
