Estado: AplazadaCrítica (9.3)—

The affected products expose an unauthenticated Telnet-based command line interface that could allow an attacker to modify hardware configurations, manipulate data, or factory reset 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.

Interfaz Telnet sin autenticación (AV:N, PR:N, UI:N) expuesta remotamente permite acceso no autorizado a cuentas/credenciales (T1078), manipulación de configuración y datos (T1565.001), y factory reset del dispositivo (T1529).

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.
