What is CVE-2006-4983?

Cisco's Network Access Control (NAC) systems are vulnerable due to their design, which allows quarantined devices to communicate over network protocols such as DNS, DHCP, and EAPoUDP. This loophole can be exploited by malicious actors to bypass established security measures, potentially leading to unauthorized access and communication on protected networks. Attackers can tunnel traffic through these protocols, undermining the effectiveness of NAC systems.
