1、前言
----

“中国制造2025”等国家战略的推出，以及云计算、大数据、人工智能、物联网等新一代信息技术与制造技术的加速融合，工业控制系统由从原始的封闭独立走向开放、由单机走向互联、由自动化走向智能化。在工业企业获得巨大发展动能的同时,也出现了大量安全隐患，而工业控制系统作为国家关键基础设施的“中枢神经”，其安全关系到国家的战略安全、社会稳定。

2、目标
----

**决赛采用工业互联网场景安全竞赛，竞赛围绕隐患挖掘、漏洞修补、协议分析、密码加 解密、工业互联网包括工控领域的SCADA、DCS、PCS、PLC、RTU、IED等系统或设备等相关知识、人工智能、等方面技术赛题。**

**一般来说工控设备弱口令巨多，这次也不例外**  
**使用常用弱口令  
账号admin  
密码admin**  
[![](https://shs3.b.qianxin.com/attack_forum/2021/10/attach-d90c00e4c6ae83162d62fbb6114689fd35aaff32.png)](https://shs3.b.qianxin.com/attack_forum/2021/10/attach-d90c00e4c6ae83162d62fbb6114689fd35aaff32.png)  
**成功进入后台(这已经拿了中危的分了)**  
**进一步挖掘，分析菜单有哪些功能点**  
**利用团队特色F12大法，刷新进行抓包**  
[![](https://shs3.b.qianxin.com/attack_forum/2021/10/attach-7410e950221e456717eebab50ff65532a2e6aeac.png)](https://shs3.b.qianxin.com/attack_forum/2021/10/attach-7410e950221e456717eebab50ff65532a2e6aeac.png)  
**发现两个post包

<http://192.168.8.143/api/v0/map/Map202105061426new/data>  
泄露用户对地图的操作记录**  
[![](https://shs3.b.qianxin.com/attack_forum/2021/10/attach-5436c5288829fc7c0597a39ee14681197fed13d2.png)](https://shs3.b.qianxin.com/attack_forum/2021/10/attach-5436c5288829fc7c0597a39ee14681197fed13d2.png)  
**泄露地图信息坐标**  
[![](https://shs3.b.qianxin.com/attack_forum/2021/10/attach-f8ca3ca78c9205d641140c09d3a19cb121011a38.png)](https://shs3.b.qianxin.com/attack_forum/2021/10/attach-f8ca3ca78c9205d641140c09d3a19cb121011a38.png)  
**未授权:以上接口无痕浏览器也可浏览  
那我们进地图列表里面**  
[![](https://shs3.b.qianxin.com/attack_forum/2021/10/attach-15a6cc3fdd69e191a9c81b478616c118669c2db8.png)](https://shs3.b.qianxin.com/attack_forum/2021/10/attach-15a6cc3fdd69e191a9c81b478616c118669c2db8.png)

**进行导出操作  
分别得到地址:  
<http://192.168.8.143/api/v0/map/Map202105061426new/export?type=FMS>  
<http://192.168.8.143/api/v0/map/Map202105061426new/export?type=OM>**

**使用无痕浏览器进行访问**  
[![](https://shs3.b.qianxin.com/attack_forum/2021/10/attach-434d5c0e00b6ba9949feaffdae4d1583ca5762d9.png)](https://shs3.b.qianxin.com/attack_forum/2021/10/attach-434d5c0e00b6ba9949feaffdae4d1583ca5762d9.png)  
**也可以进行下载  
当然Map202105061426new是有规律的，可以利用规律进行爆破，就可以下载其他地图了(给了中危)**

#### 高危漏洞

**既然要高危，不是拿到权限就是重要的信息泄露  
进入账号管理**  
[![](https://shs3.b.qianxin.com/attack_forum/2021/10/attach-6504f7dff42e4e5c44dbb6ff509ee646a9cd54b0.png)](https://shs3.b.qianxin.com/attack_forum/2021/10/attach-6504f7dff42e4e5c44dbb6ff509ee646a9cd54b0.png)  
[![](https://shs3.b.qianxin.com/attack_forum/2021/10/attach-d123c14133555cba237425c6d58b3949d22d9f58.png)](https://shs3.b.qianxin.com/attack_forum/2021/10/attach-d123c14133555cba237425c6d58b3949d22d9f58.png)  
**抓到接口http://192.168.8.143/api/v0/accounts**  
[![](https://shs3.b.qianxin.com/attack_forum/2021/10/attach-785d841b564174266af6b4598302839daadbe937.png)](https://shs3.b.qianxin.com/attack_forum/2021/10/attach-785d841b564174266af6b4598302839daadbe937.png)  
**很好，接口直接泄露所有用户密码，尝试是否有未授权，使用无痕浏览器进行前台访问**  
[![](https://shs3.b.qianxin.com/attack_forum/2021/10/attach-197e74bec836ddb2f3f71ac18a3e104ce60b38eb.png)](https://shs3.b.qianxin.com/attack_forum/2021/10/attach-197e74bec836ddb2f3f71ac18a3e104ce60b38eb.png)  
**这高危不就来了嘛**  
**既然那么多未授权，是不是可以联想到添加用户存不存在未授权呢，说干就干**  
[![](https://shs3.b.qianxin.com/attack_forum/2021/10/attach-50b3ab863ed47ed210e3134e9a3eef913676b532.png)](https://shs3.b.qianxin.com/attack_forum/2021/10/attach-50b3ab863ed47ed210e3134e9a3eef913676b532.png)

**我们直接选管理员，填完抓包**  
[![](https://shs3.b.qianxin.com/attack_forum/2021/10/attach-007e35a973112a051ed7ba630405d218248626fa.png)](https://shs3.b.qianxin.com/attack_forum/2021/10/attach-007e35a973112a051ed7ba630405d218248626fa.png)  
**可以发现并没有验证cookies也就是说只要找到这个接口就能添加用户甚至是管理员**

**添加成功**  
**有些报告忘记保存了，就这样吧**

总结
--

**最后也是通过这一台小车就拿下第七，毕竟第一次接触工控**  
**纪念一下**

**工控类安全比较缺乏，一般来说未授权存在的漏洞比较多，可以往这方面进行挖掘**
