Session theft via insufficient session expiration
Published Sep 9, 2026 · Updated Sep 9, 2026
Insufficient session expiration in Dell Secure Connect Gateway 5.0 allows remote authenticated users to steal active sessions. Dell has not disclosed which session lifecycle handler fails to invalidate or expire tokens, or the request sequence that preserves them. Exploitation requires low-privileged remote access and yields reuse of another active session, with confidentiality loss but no reported data modification or service interruption.
