"According to its its self-reported version number, the version of Jenkins running on the remote web server is Jenkins
LTS prior to 2.361.1 or Jenkins weekly prior to 2.363. It is, therefore, affected by a vulnerability:

  - In Eclipse Jetty HTTP/2 server implementation, when encountering an invalid HTTP/2 request, the error
    handling has a bug that can wind up not properly cleaning up the active connections and associated
    resources. This can lead to a Denial of Service scenario where there are no enough resources left to
    process good requests. (CVE-2022-2048)

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