This repository contains a single Metasploit module targeting a command injection vulnerability (CVE-2020-35578) in Nagios XI versions prior to 5.8.0. The exploit requires valid admin credentials and leverages the /admin/monitoringplugins.php endpoint to upload a malicious plugin file, resulting in remote code execution as the 'apache' user. The module supports both Meterpreter and bash reverse shell payloads, and is weaponized for operational use. The code is written in Ruby and follows the standard Metasploit module structure, utilizing HTTP requests to interact with the target and manage authentication, payload delivery, and cleanup. The main fingerprintable endpoints are the vulnerable HTTP path and the plugin directory on the target system.
