CVE-2024-38888

Account takeover via client-side password validation

Published Aug 2, 2024 · Updated Jul 5, 2026

Password brute forcing in Horizon Cloud Caterease 16.0.1.1663 through 24.0.1.2405 allows local users to access accounts. The login screen enables its OK button only after a correct password is entered, testing candidate passwords locally without sending failed attempts to the server. Local access to the client permits unlimited, unlogged guesses; a correct guess grants the compromised account's access to application data and actions.
