A VPN extends a corporate network through encrypted connections made over the Internet. Because the traffic is encrypted between the device and the network, traffic remains private as it travels. An employee can work outside the office and still securely connect to the corporate network. Even smartphones and tablets can connect through a VPN. To help customers determine their exposure to vulnerabilities in Cisco IOS and IOS XE Software, Cisco provides the Cisco Software Checker to identify any Cisco Security Advisories that impact a specific software release and the earliest release that fixes the vulnerabilities described in each advisory (“First Fixed”). Cisco has rolled out fixes for multiple critical vulnerabilities in the web-based management interface of Small Business routers that could potentially allow an unauthenticated, remote attacker to execute arbitrary code as the root user on an affected device.

TypeVPN software

Cisco Systems VPN Client is a software application for connecting to virtual private networks based on Internet Key Exchange version 1.

On July 29, 2011, Cisco announced the end of life of the product. No further product updates were released after July 30, 2012, and support ceased on July 29, 2014.[4] The Support page with documentation links was taken down on July 30, 2016, replaced with an Obsolete Status Notification.[5]

Availability and compatibility[edit]

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.

The open-source vpnc client can connect to most VPNs supported by the official client.

VPN Client beta added support for Mac OS X 10.6.[6] Stable version appears to lack that support; explicitly did not support versions of Mac OS X later than 10.5.[7]

VPN Client added support for 64-bit versions of Windows Vista and Windows 7.[8]

The client uses profile configuration files (.pcf) that store VPN passwords either hashed with type 7, or stored as plaintext. A vulnerability has been identified,[9] and those passwords can easily be decoded using software or online services.[10] 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).[9]
