Description

This module exploits CVE-2020-5791, an OS command injection vulnerability in
`admin/mibs.php` that enables an authenticated user with admin privileges to achieve
remote code execution as either the `apache` user or the `www-data` user on NagiosXI
version 5.6.0 to 5.7.3 inclusive (exact user depends on the version of NagiosXI
installed as well as the OS its installed on).

Valid credentials for a Nagios XI admin user are required. This module has
been successfully tested against Nagios XI 5.7.3 running on CentOS 7.
