CVE-2023-31173

Local authentication bypass via hard-coded credentials

Published Aug 31, 2023 · Updated Oct 1, 2024

Authentication bypass in SEL Grid Configurator before 4.5.0.20 allows local users to access protected functionality via hard-coded credentials. The software contains a fixed credential used by its authentication logic, but public advisories do not identify the exact file, function, or request path. Exploitation requires local access to the Windows application; the published record describes confidentiality and integrity impact, with availability impact assessed differently by CVSS sources.
