This module exploits a PHP code injection vulnerability DataLife Engine 9.7. The vulnerability exists in preview.php, due to an insecure usage of preg_replace() with the e modifier, which allows to inject arbitrary php code, when there is a template installed which contains a [catlist] or [not-catlist] tag, even when the template isn't in use currently. The template can be configured with the TEMPLATE datastore option.

To display the available options, load the module within the Metasploit console and run the commands 'show options' or 'show advanced':
msf > use exploit/unix/webapp/datalife_preview_exec
msf exploit(datalife_preview_exec) > show targets
...targets...
msf exploit(datalife_preview_exec) > set TARGET < target-id >
msf exploit(datalife_preview_exec) > show options
...show and set options...
msf exploit(datalife_preview_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.
