CVE-2023-26288Network attack vector

User impersonation via persistent pre-change sessions

Published Jul 30, 2024 · Updated Aug 2, 2024

Insufficient session expiration in IBM Aspera Orchestrator 4.0.1 allows remote authenticated users to impersonate another user. The password-change flow leaves sessions issued before the change valid instead of revoking them. Exploitation requires possession of another user's authenticated session before that user's password changes; the retained session preserves that user's application access.
