The remote Oracle Linux 8 host has packages installed that are affected by multiple vulnerabilities as referenced in the ELSA-2020-5493 advisory.
Go before 1.14.12 and 1.15.x before 1.15.4 allows Denial of Service. (CVE-2020-28362)
Go before 1.14.8 and 1.15.x before 1.15.1 allows XSS because text/html is the default for CGI/FCGI handlers that lack a Content-Type header. (CVE-2020-24553)
Go before 1.14.12 and 1.15.x before 1.15.5 allows Code Injection. (CVE-2020-28366)
Go before 1.14.12 and 1.15.x before 1.15.5 allows Argument Injection. (CVE-2020-28367)
Note that Nessus has not tested for this issue but has instead relied only on the application’s self-reported version number.
