Subject: Re: Cross site scripting & fullpath disclosure

The solution to this is to insert the following code in sp_helper_functions.php at line 10:

if (!file_exists(stripslashes($input_dir)))
	return array();

This should come immediatly before the original line 10 which is:		

$dh  = opendir(stripslashes($input_dir));	

This is alters function getDirList which should now read as follows:

//THIS FUNCTION WILL RETURN A SORTED ARRAY OF ALL FILES AND FOLDERS IN THE CURRENT DIRECTORY
function getDirList($input_dir="") 
{
	global $dir;
	if($input_dir == '')
		$input_dir = $dir;
	//echo "--" . stripslashes($input_dir) , "--";
	
	// the following is a fix for http://nvd.nist.gov/nvd.cfm?cvename=CVE-2006-6273
	// by James Brown 10:53 AM 12/27/2006
	if (!file_exists(stripslashes($input_dir)))
		return array();
		
	$dh  = opendir(stripslashes($input_dir));	
	while (false !== ($filename = readdir($dh))) 
	{
	  	$files[] = $filename;
	}
	@sort($files);
	return $files;
}
