CVE-2023-4094Network attack vector

Account lockout via unrestricted failed login requests

Published Sep 19, 2023 · Updated Sep 25, 2024

Weak authentication in Fujitsu ARCONTE-Áurea before 1.5.0.0 allows remote attackers to lock legitimate accounts through failed logins. The authentication system accepts repeated incorrect access requests, and an unidentified resource bypasses the login form's attempt limit. No authentication or user interaction is required, and mass lockout interrupts legitimate access to the service.
