Description
Stateful session bean identifiers are not generated from a cryptographically secure random source. A remote attacker with access to the EJB remote endpoint who holds one valid identifier can derive those of other clients' sessions and invoke methods on their beans, exposing or modifying other users' session state.
Users are recommended to upgrade to version 10.3.0 or 11.0.0-M2, which fix the issue.
Affected product named by the advisory: Apache TomEE.
