CVE-2020-5180 Information

Description

Viscosity 1.8.2 on Windows and macOS allows an unprivileged user to set a subset of OpenVPN parameters which can be used to load a malicious library into the memory of the OpenVPN process leading to limited local privilege escalation. (When a VPN connection is initiated using a TLS/SSL client profile the privileges are dropped and the library will be loaded resulting in arbitrary code execution as a user with limited privileges. This greatly reduces the impact of the vulnerability.)
