The Gadget API in Atlassian Jira Server and Data Center in affected versions allows remote attackers to make Jira unresponsive via repeated requests to a certain endpoint in the Gadget API. The affected versions are before version 8.5.4, and from version 8.6.0 before 8.6.1.

According to its self-reported version number, the instance of Atlassian Jira hosted on the remote web server is prior to version 8.5.4 or 8.6.0 prior to 8.6.1. It is, therefore, affected by a vulnerability which permits remote attackers to make Jira unresponsive via repeated requests to a certain endpoint in the Gadget API.

Note that the scanner has not tested for these issues but has instead relied only on the application's self-reported version number.

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.
