Description:
Some vulnerabilities have been reported in Cisco VPN Client, which can be exploited by malicious, local users to gain escalated privileges.
1) An error when using a VPN profile configured to use the Microsoft Dial-Up Networking Interface can be exploited to run arbitrary commands with the privileges of the LocalSystem account by enabling the "Start Before Logon" feature.
The vulnerability is reported in versions prior to 4.8.02.0010.
2) Incorrect permissions are set for cpvnd.exe during the Cisco VPN Client installation. This can be exploited by interactive users to run arbitary commands with the privileges of the LocalSystem account by replacing cvpnd.exe with an arbitrary file.
The vulnerability is reported in versions prior to 5.0.01.0600.
