Green Packet DX-350 uses default credentials


CWE-255: Credentials Management - CVE-2016-6552

Green Packet DX-350 uses non-random default credentials of: root:wimax. A remote network attacker can gain privileged access to a vulnerable device.


A remote attacker can take complete control of a device using default admin credentials.


The CERT/CC is currently unaware of a practical solution to this problem.

Restrict access and use strong passwords

As a general good security practice, only allow trusted hosts to connect to the device. Use of strong, unique passwords can help reduce the efficacy of brute force password guessing attacks.
