A CRC16-based algorithm for generating Technical Service credentials could allow an attacker to derive the credentials from the devices serial number and misuse them to gain unauthorized access.

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.

CWE-321 (uso de criptografía débil) en credenciales TSC derivables del número de serie permite acceso no autorizado a dispositivos SMA en red adyacente (AV:A). Impacto: autenticación comprometida y potencial control de cuenta de servicio.

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.
