CVE-2006-4982 - Gammy Young

Description

Cisco NAC maintains an exception list that does not record device properties other than MAC address which allows physically proximate attackers to bypass control methods and join a local network by spoofing the MAC address of a different type of device as demonstrated by using the MAC address of a disconnected printer.
