Technical details
The OpenEJB standalone server's admin service lacks authentication controls on stop operations, enabling an unauthenticated local attacker to send shutdown commands. The admin service is enabled by default and listens on the loopback interface, making it accessible to any local user or process on the host. Exploitation results in immediate denial of service by terminating the server process.

- Apache OpenEJB before 10.3.0 and before 11.0.0-M2
