description

Apache TomEE stateful EJB session passivation can use an unvalidated client-controlled identifier when selecting its session-state file. An attacker able to reach the remote EJB service may access session-state files outside the intended passivation storage directory.

mitigation

Upgrade Apache TomEE to 10.3.0 or 11.0.0-M2. Where applicable, 10.0.0-M1 is also recorded as a fixed release.

fixed in 10.0.0-M1, 10.3.0, 11.0.0-M2
