The version of Moodle installed on the remote host is 3.5.x prior to 3.5.18, 3.8.x prior to 3.8.9, 3.9.x prior to 3.9.7 or 3.10.x prior to 3.10.4. It is, therefore, affected by multiple vulnerabilities:

 - An authorization issue allowing teachers to export a CSV file containing forums from all courses. (CVE-2021-32472)

 - An information disclosure allowing students to see their quiz grade through the quiz web service before its release. (CVE-2021-32473)

 - An SQL injection on MNet enabled sites via an XML RPC call from the connected peer host for site administrators or users having access to the keypair. (CVE-2021-32474)

 - A stored Cross-Site Scripting vulnerability through the ID number displayed in the quiz grading report. (CVE-2021-32475)

 - A Denial of Service (DoS) due to user file upload limits not being enforced in the draft files area. (CVE-2021-32476)

 - An information disclosure exposing the last time a user accessed the mobile page on its profile page. (CVE-2021-32477)

 - A Cross-Site Scripting (XSS) and open redirect lnerability through the redirect URI of the the LTI authorization endpoint. (CVE-2021-32478)

 - A vulnerable H5P PHP version 1.24 embedded library.

Note that the scanner has not attempted to exploit this issue but has instead relied only on application's self-reported version number.

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available.

  - An SQL injection risk existed on sites with MNet enabled and configured, via an XML-RPC call from the     connected peer host. Note that this required site administrator access or access to the keypair. Moodle     3.10 to 3.10.3, 3.9 to 3.9.6, 3.8 to 3.8.8, 3.5 to 3.5.17 and earlier unsupported versions are affected.
    (CVE-2021-32474)

Note that Nessus relies on the presence of the package as reported by the vendor.
