1. 漏洞描述

ECSHOP支付插件存在SQL注入漏洞,此漏洞存在于/includes/modules/payment/alipay.php文件中,该文件是ECshop的支付宝插件。由于ECShop使用了str_replace函数做字符串替换,黑客可绕过单引号限制构造SQL注入语句。只要开启支付宝支付插件就能利用该漏洞获取网站数据,且不需要注册登入。GBK与UTF-8版本ECshop均存在此漏洞

4. 漏洞代码分析

/includes/modules/payment/alipay.php

复制代码
function respond()
{
    if (!empty($_POST))
    {
        foreach($_POST as $key => $data)
        {
        $_GET[$key] = $data;
        }
    }
    $payment  = get_payment($_GET['code']);
    $seller_email = rawurldecode($_GET['seller_email']);
    $order_sn = str_replace($_GET['subject'], '', $_GET['out_trade_no']);
    //未对$order_sn进行有效注入过滤
    $order_sn = trim($order_sn);  
    ..
复制代码

ECShop在/includes/init.php中有段代码会将外界传入的数据进行转义,比如单引号;同样在/includes/modules/payment/alipay.php中外界传入的GET[subject]_GET['out_trade_no']也是被转义过的,但是在该文件的str_replace()函数会将GET[outtradeno]_GET['subject']过滤掉(黑客输入转义符号,将转义符本身过滤叼),最后经过str_replace()函数处理后引入单引号,使闭合单引号重新获得攻击能力,触发SQL注入

5. 防御方法

/includes/modules/payment/alipay.php

复制代码
function respond()
{
    if (!empty($_POST))
    {
        foreach($_POST as $key => $data)
        {
        $_GET[$key] = $data;
        }
    }
    $payment  = get_payment($_GET['code']);
    $seller_email = rawurldecode($_GET['seller_email']);
    $order_sn = str_replace($_GET['subject'], '', $_GET['out_trade_no']);
    /* 对$order_sn进行有效过滤 */
    $order_sn = trim(addslashes($order_sn));
    /* */
    ..
