Published: 2014-03-19 06:24:59

CVSS Base Vector:
AV:N/AC:L/Au:N/C:C/I:N/A:N

Summary:
This host is running Quantum DXi and is prone to authentication bypass vulnerability.

Detection Method:
Send a SSH Private Key and check whether it is possible to login to the target machine

Technical Details:
- The root user has a hardcoded password that is unknown and not changeable. Normally access is only through the restricted shells. - The /root/.ssh/authorized_keys on the appliance contains the static private ssh key. Using this key on a remote system to login through SSH will give a root shell.

Impact:
Successful exploitation will allow attacker to gain unauthorized root access to affected devices and completely compromise the devices.
