8.0.0.13, 8.5.0.x prior to 8.5.5.11 or 9.0.x prior to 9.0.0.1. It is, therefore, affected by a denial of service
vulnerability in the Apache Commons FileUpload subcomponent. An unauthenticated, remote attacker can exploit this, by
sending file upload requests, in order to cause the server to become unresponsive.

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version
