Cisco Systems VPN Client
Cisco VPN Client on Windows 7.
|Preview release||4.9.01.0230 for Mac / July 27, 2010|
|Operating system||Windows, Mac OS X 10.4 and 10.5, Solaris UltraSPARC, Linux (Intel)|
The Cisco Systems VPN Client was a software application for connecting to a virtual private network. The client makes remote resources of another network available in a secure way as if the user was connected directly to that "private" network.
In July 2011, Cisco announced the end of life of the product. No further product updates were released after July 2012, and support will cease in 2014. A suggested migration option for customers is the Cisco AnyConnect Secure Mobility Client.
The client is normally distributed with an executable installer and profile file(s), which contain all the necessary information to easily connect to a network.
A .pcf (or profile configuration file) is used to configure the VPN client for connecting to the remote server.
The software is not free but is often installed on university and business computers in accordance with a site-license. As with most corporate licenses, administrators are allowed to freely distribute the software to users within their network.
VPN Client 4.9.01.0230 beta added support for Mac OS X 10.6. Stable version 4.9.01.0180 appears to lack that support; 4.9.00.0050 explicitly did not support versions of Mac OS X later than 10.5.
VPN Client 5.0.07.0290 added support for 64-bit versions of Windows Vista and Windows 7.
The client uses profile files (.pcf) that store VPN passwords either hashed with type 7, or stored as cleartext. A vulnerability has been identified, and those passwords can easily be decoded using software or online services. To work around these issues, network administrators are advised to use the Mutual Group Authentication feature, or use unique passwords (that aren't related to other important network passwords).
