CVE-2023-4335Network attack vector

Unauthenticated private file disclosure via nginx

Published Aug 15, 2023 · Updated Oct 8, 2024

Missing authentication in the nginx server for LSI Storage Authority before 7.017.011.000 allows remote attackers to read private files. On Linux, the bundled nginx web server exposes private server-side files without requiring a session or credentials. Network reachability to the management web service is sufficient; published records do not identify the exposed paths or file contents.
