CVE-2018-10169 Information

Description

ProtonVPN 1.3.3 for Windows suffers from a SYSTEM privilege escalation vulnerability through the \ProtonVPN Service\ service. This service establishes an NetNamedPipe endpoint that allows arbitrary installed applications to connect and call publicly exposed methods. The \Connect\ method accepts a class instance 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. This plugin will execute code in the context of the SYSTEM user.
