CyberGhost 6.5.0.3180 for Windows suffers from a SYSTEM privilege escalation vulnerability through the CG6Service service. This service establishes a NetNamedPipe endpoint that allows arbitrary installed applications to connect and call publicly exposed methods. The ConnectToVpnServer method accepts a connectionParams argument that provides attacker control of the OpenVPN command line. An attacker can specify a dynamic library plugin that should run for every new VPN connection attempt. This plugin will execute code in the context of the SYSTEM user.
The product specifies permissions for a security-critical resource in a way that allows that resource to be read or modified by unintended actors.
