Windows Authenticated Scan

Hello Everyone.

Perhaps someone could help me identify what I am doing wrong, or what should I check.

I have the GVM Community Edition installed standalone on a dedicate Ubuntu VM. I’m trying to set up authenticated scans for my Windows machines (both desktop and server), and I am running into tons of issues.

Every single test scan I run results in multiple errors related to Windows SMB Login, many applications are not found etc.

I went through the documentation and I think I checked all the boxes:

  • Domain account has been provisioned and added to the local administrators group on my machines.
  • LocalAccountTokenFilterPolicy is set to 1
  • Remote registry service is running and set to automatic
  • Firewall is configured to allow incoming SMB and WMI traffic

Yet when I run the tests, this is what happens

  • When testing from the GVM server using smbclient -U greenbone@domain.local -L //TARGET I can see the default ADMIN$, C$ and IPC$ shares (and other shares if created)
    • I am getting SMB1 errors, but that’s not surprising as it’s disabled
  • On the servers I can see successful logon events for greenbone@domain.local in the Security logs, though I can’t see it on the workstation for some reason
  • No errors in the SMBServer log
  • Can’t see any errors in the /var/log/gvm/* logs
  • The Windows 11 scan shows only two applications:
    • TLS 1.2
    • TLS 1.3
  • The Windows Server scan shows only Microsoft applications, but does not detect anything 3rd party.

I’ve already spent too much time trying to get this to work, and I am out of ideas.

Perhaps someone could point me in the right direction?

Many thanks in advance.

Wojciech
