Solution

No solution given by the vendor.


Workaround

Discontinue the use of allowing remote sessions to be issued from the local device to reach loopback address(es). It is good security practice to limit the exploitable attack surface of critical infrastructure networking equipment. Use access lists or firewall filters to limit access to the device from trusted, administrative networks or hosts.
