All the vulnerabilities described in this security advisory can be mitigated by
disabling management access to the affected system GUI.
Administrators can use the interfaceconifg
command to disable appliance management via the GUI. Alternatively, this can be done via the
GUI by editing the management interface properties under Network->IP
interfaces-> Edit and then selecting Disable Appliance Management.
Administrators can manage the affected system via SSH and command-line interface while GUI access is
disabled. However, not all commands and features may be available via command-line interface.
Administrators can also limit the attack surface by restricting IP
addresses that can access the management interface. This can be
done using the adminaccessconfig
command and selecting IPACCESS
from the menu.
Administrator should also implement Cross-Site Request Forgery protection if available on their platform and software release. This will help limit the attack surface of the command injection vulnerabilities, although will not completely eliminate them.
