Account enumeration via distinguishable server responses
Published Nov 12, 2025 · Updated Nov 12, 2025
Observable response discrepancy in Omnissa Workspace ONE UEM allows remote attackers to enumerate tenant IDs and user accounts. Workspace ONE UEM returns distinguishable responses for valid and invalid tenant IDs or user accounts, but Omnissa has not identified the affected endpoint. No authentication or user interaction is required, and the exposed identifiers can support brute-force, password-spraying, or credential-stuffing attacks.
