CVE-2022-43978Network attack vector

Authenticated access bypass via static public-hash secret

Published Jan 27, 2023 · Updated Mar 27, 2025

Improper authentication in Pandora FMS 764 allows remote authenticated users to bypass an authentication check with valid session data. The generatePublicHash function derives its public hash from a static secret, so valid session data can satisfy checks intended to establish identity. Exploitation requires knowledge of a valid session and user interaction, and it can expose or alter protected information without interrupting service.
