10.10.10.15
port 80 is open.
The website is under construction, but running IIS 6.0
Able to log in to WebDAV using cadaver with no credentials.

We're even able to upload files.

I am unable to upload asp files, they seem to be filtered, but we can add a .txt extension for upload then rename once it's up there.
I copied /usr/share/webshells/aspx/cmdasp.aspx to the webserver but it doesn't appear to work.

We see this is 32bit

We generate a reverse shell using msfvenom and upload the same way we did with the webshell.
We used Windows-Exploit-Suggester which found a few exploits, none which worked. Then we searched on google for Windows Server 2003 privilege escallation and found Churrasco.
Using Churrasco (MS09-012) we are able to run commands as system:

We copy over netcat and get a shell that way.

Now we can collect the user flag: c:\documents and settings\lakis\desktop\user.txt and the root flag c:\documents and settigns\administrator\desktop\root.txt
