Input passed to the "RP_PATH" 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.  

code from index.php

<?php
        require "pp-inc.php";

if ( is_numeric($argv[0]) ) {
    header("Location: 
{$Globals['maindir']}/showproduct.php?product={$argv[0]}");
    exit;
}

require "$RP_PATH/languages/$rplang/index.php";
require "$RP_PATH/login-inc.php";

if ( file_exists("install.php") || 
file_exists("{$Globals['maindir']}/install.php") ) {
    diewell( "For security reasons, please remove the install.php from the 
ReviewPost directory before proceeding." );
    exit;
}

?>

nb : others file has vulnerable too :)
