 Privilege Escalation Vulnerabilities

I went to the below URL you referenced
(http://www.cisco.com/cgi-bin/tablebuild.pl/windows?psrtdcat20e2), logged
in, and it works fine for me with a listing of all the clients to
download.

vpnclient-win-msi-5.0.01.0600-k9.exe
VPN Client Software for 2000/XP/Vista - Microsoft Installer 	5.0.01.06
	23-JUL-2007 	10676224

I would suggest getting an account if you do not have one.  That would
definitely make downloading the client from that URL a lot easier.
