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 2def7c4b-736f-4754-9f03-236fcb586d91 advisory.
Note that Nessus has not tested for this issue but has instead relied only on the application’s self-reported version number.

"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 2def7c4b-736f-4754-9f03-236fcb586d91 advisory.
- Wagtail is an open source content management system built on Django. Prior to versions 4.1.4 and 4.2.2, a
memory exhaustion bug exists in Wagtail's handling of uploaded images and documents. For both images and
documents, files are loaded into memory during upload for additional processing. A user with access to
upload images or documents through the Wagtail admin interface could upload a file so large that it
results in a crash of denial of service. The vulnerability is not exploitable by an ordinary site visitor
without access to the Wagtail admin. It can only be exploited by admin users with permission to upload
images or documents. Image uploads are restricted to 10MB by default, however this validation only happens
on the frontend and on the backend after the vulnerable code. Patched versions have been released as
Wagtail 4.1.4 and Wagtail 4.2.2). Site owners who are unable to upgrade to the new versions are encouraged
to add extra protections outside of Wagtail to limit the size of uploaded files. (CVE-2023-28837)
Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version
number.");
