"The remote MiracleLinux 8 host has packages installed that are affected by a vulnerability as referenced in the
AXSA:2020-740:02 advisory.

    .NET Core is a managed-software framework. It implements a subset of the .NET framework APIs and several
    new APIs, and it includes a CLR implementation.
    New versions of .NET Core that address security vulnerabilities are now available. The updated versions
    are .NET Core SDK 3.1.108 and .NET Core Runtime 3.1.8.
    Security Fixes:
      * .NET Core: ASP.NET cookie prefix spoofing vulnerability (CVE-2020-1045)
    Default inclusions for applications built with .NET Core have been updated to reference the newest
    versions and their security fixes.

Tenable has extracted the preceding description block directly from the MiracleLinux security advisory.

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