Description

This module exploits a vulnerability found in GetSimpleCMS, which allows unauthenticated attackers to perform Remote Code Execution. An arbitrary file upload (PHPcode for example) vulnerability can be triggered by an authenticated user, however authentication can be bypassed by leaking the cms API key to target the session manager.

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/multi/http/getsimplecms_unauth_code_exec
msf exploit(getsimplecms_unauth_code_exec) > show targets
    ...targets...
msf exploit(getsimplecms_unauth_code_exec) > set TARGET < target-id >
msf exploit(getsimplecms_unauth_code_exec) > show options
    ...show and set options...
msf exploit(getsimplecms_unauth_code_exec) > 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.
