CVE-2024-22351Network attack vector

Authenticated impersonation via persistent logout session

Published Apr 23, 2025 · Updated Sep 1, 2025

Insufficient session expiration in IBM InfoSphere Information Server 11.7 allows remote authenticated users to impersonate another user. The DataStage Flow Designer logout API leaves the server-side session identifier valid instead of invalidating it. A valid authenticated session is required, and the retained session remains usable for actions under another user's identity.
