Summary

The internal system EJBs used for remote deployment and configuration did not enforce their administrative role check when the server ran with the default profile. A remote unauthenticated attacker able to reach the remote EJB endpoint could deploy arbitrary applications and execute code. Only installations that enabled the system applications and a remote EJB endpoint are exposed. Users are recommended to upgrade to version 10.3.0 or 11.0.0-M2, which fix the issue.
