"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 0b85b1cd-e468-11ed-834b-6c3be5272acd advisory.

  - Templates do not properly consider backticks (`) as Javascript string delimiters, and do not escape them
    as expected. Backticks are used, since ES6, for JS template literals. If a template contains a Go template
    action within a Javascript template literal, the contents of the action can be used to terminate the
    literal, injecting arbitrary Javascript code into the Go template. As ES6 template literals are rather
    complex, and themselves can do string interpolation, the decision was made to simply disallow Go template
    actions from being used inside of them (e.g. var a = {{.}}), since there is no obviously safe way to
    allow this behavior. This takes the same approach as github.com/google/safehtml. With fix, Template.Parse
    returns an Error when it encounters templates like this, with an ErrorCode of value 12. This ErrorCode is
    currently unexported, but will be exported in the release of Go 1.21. Users who rely on the previous
    behavior can re-enable it using the GODEBUG flag jstmpllitinterp=1, with the caveat that backticks will
    now be escaped. This should be used with caution. (CVE-2023-24538)

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