NAS4Free allows an authenticated user to post PHP code to a special HTTP script and have the code executed remotely. This module was successfully tested against NAS4Free version 9.1.0.1.804. Earlier builds are likely to be vulnerable as well.

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/nas4free_php_exec
msf exploit(nas4free_php_exec) > show targets
...targets...
msf exploit(nas4free_php_exec) > set TARGET < target-id >
msf exploit(nas4free_php_exec) > show options
...show and set options...
msf exploit(nas4free_php_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.
