CVE-2018-10647 Information

Description

SaferVPN 4.2.5 for Windows suffers from a SYSTEM privilege escalation vulnerability in its \SaferVPN.Service\ service. The \SaferVPN.Service\ service executes \openvpn.exe\ using OpenVPN config files located within the current user’s LOCALAPPDATA\SaferVPN\OvpnConfig directory. An authenticated attacker may modify these configuration files to 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.
