This module exploits the logic in the CartView.php page when crafting a draft email with an attachment. By uploading an attachment for a draft email, the attachment will be placed in the /tmp_attach/ folder of the ChurchInfo web server, which is accessible over the web by any user. By uploading a PHP attachment and then browsing to the location of the uploaded PHP file on the web server, arbitrary code execution as the web daemon user (e.g. www-data) can be achieved.

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