The remote switch has a denial of service vulnerability.
The remote host appears to be a Avaya Cajun switch. It was possible
to crash it by sending a malformed string to TCP port 4000. These
attacks disable the switch for thirty seconds.
A remote attacker could use this to repeatedly disable the switch,
affecting network availability.
