Username enumeration via observable response discrepancy
Published Jan 27, 2025 · Updated Jan 27, 2025
Observable response discrepancy in IBM Sterling File Gateway allows remote authenticated users to enumerate valid usernames. The myfg 2.0 interface returns observably different request responses for valid and invalid usernames, creating a username-existence oracle. An authenticated account is required; the result is limited to disclosure of valid account names, with no reported data access or modification.

Exploitability
Present is not the same as exploitable
Compare your product and version with the public record. A matching version still requires validation against your environment.
Is a vulnerable build present?
Compare these published version ranges with your installed build and any vendor patches.
- Affected versionversion=6.0.0.0 <=6.1.2.5
- Affected versionversion=6.2.0.0 <=6.2.0.1
