"The version of cmake / curl installed on the remote CBL Mariner 2.0 host is prior to tested version. It is, therefore,
affected by a vulnerability as referenced in the CVE-2023-46219 advisory.

  - When saving HSTS data to an excessively long file name, curl could end up removing all contents, making
    subsequent requests using that file unaware of the HSTS status they should otherwise use. (CVE-2023-46219)

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