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.

Time is precious, so I don’t want to do something manually that I can automate. Leveraging the Metasploit Framework when automating any task keeps us from having to re-create the wheel as we can use the existing libraries and focus our efforts where it matters.
