CVE-2023-28123

VPN credential theft via insecure startup permissions

Published Apr 19, 2023 · Updated Feb 5, 2025

Permission misconfiguration in UI Desktop for Windows 0.59.1.71 and earlier allows local users to hijack VPN credentials during startup. Ubiquiti has not published the affected permission, resource, or operation that exposes those credentials. Exploitation requires local access and the UID VPN startup sequence, and the reported consequence is credential disclosure rather than modification or service interruption.
