CVE-2006-4430 describes a vulnerability in Cisco Network Admission Control (NAC) 3.6.4.1 and earlier, allowing remote attackers to hinder the installation of the Cisco Clean Access (CCA) Agent and bypass local/remote protection mechanisms. This is achieved by manipulating the HTTP User-Agent header or TCP/IP stack behavior. With a CVSS score of 5.0 (AV:N/AC:L/Au:N/C:N/I:P/A:N), the vulnerability is network-exploitable with low attack complexity, potentially leading to integrity impacts without requiring authentication. Despite the vendor disputing its severity, there is no evidence of active exploitation, public exploit code, or significant community discussion, and it is not listed in CISA's KEV catalog.
