What is CVE-2006-4430?
Certain versions of Cisco Network Admission Control (NAC) permit remote attackers to interfere with the installation of the Cisco Clean Access (CCA) Agent. By altering the HTTP User-Agent header or manipulating the TCP/IP stack behavior, an attacker can potentially bypass protective mechanisms that restrict unauthorized access. Although Cisco has disputed the impact of this issue, users should be aware of potential vulnerabilities in their systems.
