CVE-2024-36510Network attack vector

User enumeration via divergent login responses

Published Jan 14, 2025 · Updated Jan 15, 2025

Observable response discrepancy in Fortinet FortiClient EMS and FortiSOAR allows remote attackers to enumerate users via login requests. The login request handler returns observably different responses for valid and invalid usernames, creating a user-existence oracle. No authentication or user interaction is required, and the reported consequence is limited to disclosure of valid account names.
