if we login roundcube as root we also can download sources
http://drip.darkcorp.htb/dashboard/apps/.../routes.py

in source code we find new host we can login and reset pass:
http://dev-a3f1-01.drip.htb/reset/{reset_token}

So we know mechanism to reset user password
But how to get the letter with reset_token for bcase? we only can login as our user and root user.

You use the contact form to send an email with a XSS payload. This way you can exfiltrate the mails including the reset link. (Pretty sure the file download is unintended)

The POST request to 172.16.20.2/status contains a json. I don't know if we can inject commands there, the request is done via python requests. Just start a listener with ligolo pointing to your http server and modify the port of the json

{"protocol":"http","host":"drip.darkcorp.htb","port":"xxxx"}


GET / HTTP/1.1
Host: drip.darkcorp.htb:8080
User-Agent: python-requests/2.32.3
Accept-Encoding: gzip, deflate
Accept: */*
Connection: keep-alive

Edit: You can use ntlmrelay to obtain a shell from another account

I can't even make the requests pass through Burp, for some reason it gives me 401

http://172.16.20.2:5000/check this works with victor's creds.  I thought maybe i could snag a hash with responder, but I already had to jump through hoops to get access to the network, i can't just make it fetch my ip.

How did you find this ? please don't say dir fuzzing lol.
I think with ligolo you can tell him to forward one port only, that way you target the .3 machine and it is forwarded to you
