Summary

When the broker is processing message-based management requests, sent by an authenticated messaging client that is authorized with MANAGE permission to perform management-via-messaging, the parameter processing can trigger Java deserialization of certain method parameters that the broker will not utilise.

The permitted types allow to craft a payload causing excessive computation and pinning the processing thread, leading to denial of service.
