What is CVE-2020-5180?
CVE-2020-5180 is a high-severity vulnerability in n/a, published on 14 Jan 2020. It can only be exploited from the same machine or local network, with no action from the victim.
Official 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.)
