Cajun Switch Negative Integer Handling Remote DoS

high Nessus Plugin ID 11759



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.


Contact Avaya for a patch.
