"The version of FreeBSD installed on the remote host is prior to tested version. It is, therefore, affected by a
vulnerability as referenced in the 827b95ff-290e-11ed-a2e7-6c3be5272acd advisory.

  - Grafana Labs reports: On July 21, an internal security review identified an unauthorized file disclosure
    vulnerability in the Grafana Image Renderer plugin when HTTP remote rendering is used. The Chromium
    browser embedded in the Grafana Image Renderer allows for printing of unauthorized files in a PNG file.
    This makes it possible for a malicious user to retrieve unauthorized files under some network conditions
    or via a fake data source (this applies if the user has admin permissions in Grafana). (CVE-2022-31176)

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