Quantum DXi V1000 2.2.1 - Static SSH Key vulnerability in root use

Code
Details:
----------
 
[ 0x01 - Default root user ]
 
The root user has a hardcoded password that is unknown and not changeable.
Normally access is only through the restricted shells.
 
The /etc/shadow file shows the following hash:
root:$1$FGOgdWM7$dac9P0EJgTSX8a4zc4TXJ/:15783:0:99999:7:::
 
 
[ 0x02 - Known SSH Private Key ]
 
 
The /root/.ssh/authorized_keys on the appliance contains the following key
(same with every deployment):
 
-----BEGIN DSA PRIVATE KEY-----

Using the key on a remote system to login through SSH will give a root
shell:
