Unauthenticated user enumeration via token response differences
Published Mar 14, 2024 · Updated Aug 22, 2024
User enumeration in Delinea Secret Server 11.4 allows remote attackers to identify valid accounts through the Authentication REST API. The /oauth2/token endpoint returns observably different responses for valid and invalid usernames instead of using a uniform authentication failure. No authentication or user interaction is required, and the disclosure is limited to account validity rather than credentials or account access.
