"The version of Dell EMC NetWorker installed on the remote Windows host is 18.x or 19.x prior to 19.4.0.4. It is,
therefore, affected by multiple vulnerabilities, as follows:

  - Dell NetWorker, versions 18.x and 19.x contain a Path traversal vulnerability. A NetWorker server user
    with remote access to NetWorker clients may potentially exploit this vulnerability and gain access to
    unauthorized information. (CVE-2021-21569)

  - Dell NetWorker, versions 18.x and 19.x contain an Information disclosure vulnerability. A NetWorker server
    user with remote access to NetWorker clients may potentially exploit this vulnerability and gain access to
    unauthorized information. (CVE-2021-21570)

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