Detailsinfo

A vulnerability has been found in Viscosity 1.8.2 on Windows/macOS and classified as critical. This vulnerability affects an unknown function of the component OpenVPN Parameter Handler. The manipulation with an unknown input leads to a privileges management vulnerability. The CWE definition for the vulnerability is CWE-269. The product does not properly assign, modify, track, or check privileges for an actor, creating an unintended sphere of control for that actor. As an impact it is known to affect confidentiality, integrity, and availability. CVE summarizes:

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.)

The weakness was released 01/14/2020 (Website). The advisory is available at sparklabs.com. This vulnerability was named CVE-2020-5180 since 01/01/2020. Local access is required to approach this attack. The successful exploitation requires a single authentication. The technical details are unknown and an exploit is not available. This vulnerability is assigned to T1068 by the MITRE ATT&CK project.

There is no information about possible countermeasures known. It may be suggested to replace the affected object with an alternative product.
