Unauthenticated RCE in SSH due to Hardcoded Default Public/Private Keys (CWE-1394: Use of Default Cryptographic Key). Ruckus vSZ has a built-in user with all of the same privileges as root. This user also has default public and private RSA keys in its /home/$USER/.ssh/ directory. Anyone with a Ruckus device would also have this private key and be able to ssh as this and then have root-level permissions.
