首先看 index.php

加载了下面这些文件

include ‘./config/ourphp_code.php‘;
include ‘./config/ourphp_config.php‘;
include ‘./config/ourphp_version.php‘;
include ‘./config/ourphp_Language.php‘;
include ‘./function/ourphp_function.class.php‘;
include ‘./function/ourphp/Smarty.class.php‘;
include ‘./function/ourphp_system.class.php‘;
include ‘./function/ourphp_template.class.php‘;

其中 ourphp_function.class.php 为一些安全过滤函数

批量搜索 $_POST

挑了一处跟进去  

\client\manage\ourphp_articleview.php  第71行

$query = $db -> update("`ourphp_article`","`OP_Articletitle` = ‘".admin_sql($_POST["OP_Articletitle"])."‘,`OP_Articleauthor` = ‘".admin_sql($_POST["OP_Articleauthor"])."‘,`OP_Articlesource` = ‘".admin_sql($_POST["OP_Articlesource"])."‘,`time` = ‘".date("Y-m-d H:i:s")."‘,`OP_Articlecontent` = ‘".admin_sql($_POST["OP_Articlecontent"])."‘,`OP_Tag` = ‘".$wordtag."‘,`OP_Class` = ‘".$OP_Articleclass[0]."‘,`OP_Lang` = ‘".$OP_Articleclass[1]."‘,`OP_Sorting` = ‘".admin_sql($_POST["OP_Articlesorting"])."‘,`OP_Attribute` = ‘".$OP_Articleattribute."‘,`OP_Url` = ‘".admin_sql($_POST["OP_Articleurl"])."‘,`OP_Description` = ‘".compress_html($OP_Articlecontent)."‘,`OP_Minimg` = ‘".$OP_Minimg."‘","where id = ".intval($_GET[‘id‘]));

发现大部分参数都经过了 admin_sql 函数的处理,但是发现 $OP_Articleattribute 没有经过admin_sql的处理

搜索 $OP_Articleattribute 发现

\client\manage\ourphp_articleview.php  第47-51行

        if (!empty($_POST["OP_Articleattribute"])){
        $OP_Articleattribute = implode(‘,‘,$_POST["OP_Articleattribute"]);
        }else{
        $OP_Articleattribute = ‘‘;
        }

显然也没有经过处理

这里是update 的注入点  而且没有回显 所以不能用报错注入

根据上面对 $OP_Articleattribute 知道这里应该传入数组

监控sql语句为

update `ourphp_article` set `OP_Articletitle` = ‘世界,你好!‘,`OP_Articleauthor` = ‘‘,`OP_Articlesource` = ‘‘,`time` = ‘2017-08-10 12:05:16‘,`OP_Articlecontent` = ‘世界,你好!‘,`OP_Tag` = ‘‘,`OP_Class` = ‘3‘,`OP_Lang` = ‘cn‘,`OP_Sorting` = ‘99‘,`OP_Attribute` = ‘aaaaaaaaaaaaa,xxxxxxxxx‘‘,`OP_Url` = ‘‘,`OP_Description` = ‘世界,你好!‘,`OP_Minimg` = ‘skin/noimage.png‘ where id = 3

带入了单引号

 

最后给出poc
