Nagios XI Authenticated Remote Command Execution



This module exploits a vulnerability in Nagios XI before 5.6.6 in order to execute arbitrary commands as root. The module uploads a malicious plugin to the Nagios XI server and then executes this plugin by issuing an HTTP GET request to download a system profile from the server. For all supported targets except Linux (cmd), the module uses a command stager to write the exploit to the target via the malicious plugin. This may not work if Nagios XI is running in a restricted Unix environment, so in that case the target must be set to Linux (cmd). The module then writes the payload to the malicious plugin while avoiding commands that may not be supported. Valid credentials for a user with administrative privileges are required. This module was successfully tested on Nagios XI 5.6.5 running on CentOS 7. The module may behave differently against older versions of Nagios XI. See the documentation for more information.

Module Options

To display the available options, load the module within the Metasploit console and run the commands 'show options' or 'show advanced':

msf > use exploit/linux/http/nagios_xi_authenticated_rce
msf exploit(nagios_xi_authenticated_rce) > show targets
msf exploit(nagios_xi_authenticated_rce) > set TARGET < target-id >
msf exploit(nagios_xi_authenticated_rce) > show options
    ...show and set options...
msf exploit(nagios_xi_authenticated_rce) > exploit

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.
