Technical Description
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.
Remediation
Check the references section for vendor advisories and patches from mcafee. Update tunnelbear to the latest patched version. If immediate patching is not possible, review the CVSS vector to understand the attack surface and apply compensating controls such as network segmentation or access restrictions.
