"According to its self-reported version number, the instance of Atlassian Jira hosted on the remote web server is
version 7.6.x prior to 8.5.4 or 8.6.x prior to 8.6.1. It is, therefore, affected by a denial of service (DoS)
vulnerability in the Dashboard & Gadgets component. An unauthenticated, remote attacker can exploit this issue by
sending repeated requests to a certain endpoint in the Gadget API to cause the application to become unresponsive.

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