CVE-2022-34334Network attack vector

User impersonation via session reuse after logout

Published Oct 10, 2022 · Updated Sep 16, 2024

Session fixation in IBM Sterling Partner Engagement Manager 2.0 allows remote authenticated users to impersonate another user after logout. The logout path leaves the existing session valid instead of invalidating it, so a retained session credential remains accepted. An authenticated user with another user's still-valid session credential can act as that user and perform actions in that account.
