Webdav
Port 80 just shows the default ISS page, and the smp scan result in not useful information.
I ran a nikto scan on port 80 to see if there was anything I missed. cmd used: nikto -h 192.168.198.122
The scan showed we can upload files so tried using davtest to test it but I needed credentials first.

ldap
Next I tried enumerating ldap with ldapsearch, and listed in of the descriptions is a users password.
cmd used: ldapsearch -x -H ldap://192.168.198.122 -b "DC=hutch,DC=offsec"
Using these credentials I can try and test the Webdav method I found earlier.
Davtest
cmd used:davtest -auth fmcsorley:CrabSharkJellyfish192 -sendbd auto -url http://192.168.198.122
From this scan we see that we can upload aspx files, knowing this we can upload a reverse shell.
User flag
I uploaded a reverse shell using curl and the credentials I found.
Using this shell I was able to grab the user flag.
Root Flag
After some snooping the system for any privilege escalation points. I found that the user we are signed as has Impersonation Privileges enabled.
With this we can try and perform the printerspoofer exploit.
https://itm4n.github.io/printspoofer-abusing-impersonate-privileges/
I uploaded the exploit by setting up a python server and using powershell to pull the file.
Using this exploit I was able to get administrator access.
