Description (partial)

Symptom:
A vulnerability in the TCP port management of the Cisco ONS 15454 Series Multiservice 
Provisioning Platforms could allow an unauthenticated, remote attacker to cause the c
ontroller card to unexpectedly reload.

The vulnerability is due to a specific TCP port listening on the local management port
when it should have been internal only. An attacker could exploit this vulnerability 
by sending a continuous stream of TCP traffic to the targeted device on the specific 
TCP port. An exploit could allow the attacker to cause the controller card to unexpectedly
reset. The user traffic is not impacted however the management port traffic could be
disrupted for a short duration of time.

Conditions:
This vulnerability exists in all software versions until the first fixed release. The first
fixed release is planned to be 10.62 which is being targeted for Spring 2017.
