CVE-2023-4327

Local encryption-key disclosure through unrestricted access

Published Aug 15, 2023 · Updated Nov 4, 2025

Insufficiently protected credentials in Broadcom LSI Storage Authority before 7.017.011.000 allow local users on Linux to read encryption keys. The public record states that the web interface's encryption keys are accessible to every local account but does not identify the storage path or faulty access-control operation. A low-privileged local account is required; access exposes protected controller data without reported integrity or availability impact.
