the following:

 - A command injection vulnerability in the file /usr/local/nagiosxi/html/includes/configwizards/windowswmi/windowswmi.inc.php
   due to improper sanitization of authenticated user-controlled input by a single HTTP request (CVE-2021-25296).

 - A command injection vulnerability in the file /usr/local/nagiosxi/html/includes/configwizards/switch/switch.inc.php
   due to improper sanitization of authenticated user-controlled input by a single HTTP request (CVE-2021-25297).

 - A command injection vulnerability in the file /usr/local/nagiosxi/html/includes/configwizards/cloud-vm/cloud-vm.inc.php
   due to improper sanitization of authenticated user-controlled input by a single HTTP request (CVE-2021-25298).

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