CVE-2018-10381
TunnelBear 3.2.0.6 for Windows suffers from a SYSTEM privilege escalation vulnerability through the "TunnelBearMaintenance" service.
Impact
TunnelBear 3.2.0.6 for Windows suffers from a SYSTEM privilege escalation vulnerability through the "TunnelBearMaintenance" service. This service establishes a NetNamedPipe endpoint that allows arbitrary installed applications to connect and call publicly exposed methods. The "OpenVPNConnect" method accepts a server list 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.
