Authenticated username disclosure via undisclosed REST endpoint
Published Aug 14, 2024 · Updated Aug 16, 2024
Information disclosure in F5 BIG-IP allows remote authenticated users to obtain user account names through iControl REST requests. F5 identifies an undisclosed iControl REST endpoint that returns a username list but has not published the endpoint or faulty authorization logic. A low-privileged account and network access to iControl REST are required; the reported consequence is limited to account-name disclosure.
