This website requires authentication, via POST. However, it seems as if someone has defaced our site. Maybe there is still some way to authenticate? http://165.227.106.113/post.php
Solution:
You need to send a POST request.
The website also has the username and password you need to send in and html comment on the page.
username: admin | password: 71urlkufpsdnlkadsf
curl -d "username=admin&password=71urlkufpsdnlkadsf" -X POST http://165.227.106.113/post.php
Returns: <h1>flag{p0st_d4t4_4ll_d4y}</h1>
Flag: flag{p0st_d4t4_4ll_d4y}
