CVE-2022-24032Network attack vector

Username enumeration via distinct login errors

Published Jan 30, 2022 · Updated Aug 3, 2024

User enumeration in Adenza AxiomSL ControllerView 10.8.1 and earlier allows remote attackers to identify valid usernames via login attempts. The login handler returns a different error message when a submitted username is valid, exposing account existence before authentication. No account or user interaction is required, and the disclosed usernames can support password guessing or other account-targeting attacks.
