CVE-2022-28812Network attack vector

Unauthenticated SuperUser access via hard-coded credentials

Published Sep 28, 2022 · Updated May 20, 2025

Hard-coded credentials in Carlo Gavazzi UWP 3.0 before 8.5.0.3 and CPY Car Park Server before 2.8.3 allow remote attackers to gain SuperUser access. CERT@VDE identifies hard-coded credentials in the devices but does not disclose the account, credential, or authentication endpoint that accepts them. No prior authentication or user interaction is required, and successful use grants full administrative control of the affected device.
