OpenVAS installed on Kali Linux. Feeds are fully up-to-date and openvas-check-setup suggests everything working OK
Target host is a standalone (i.e. not domain-joined) Windows laptop which hasn’t been updated for months. Connectivity between these hosts is fine.
Local administrator on the target host account enabled and password set.
Running a credentialed Nessus scan of the laptop from my iMac finds dozens of missing patches as expected.
OpenVAS full & fast credentialed scan from Kali finds only three minor issues. No missing patches detected at all. Just to check, I installed OpenVAS on the iMac as well and the same result was obtained.
Remote registry service on the laptop is running and registry key HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\Policies\system\LocalAccountTokenFilterPolicy has been set and laptop rebooted.
I have moved the topic to the correct category for now. It could be possible that the info above is made more prominent / easier to find in the future.
To solve your initial issue you might want to give the following hints (and the other threads linked within it) a try:
Can you please tell me the actual procedure or any related document for configuring openVAS for detecting missing Windows patches in a windows target machine ?
Didn’t work for me. Remote registry running on a target Windows Server 2012R. A full and fast scan gets only enumeration of the ports. Using a local user other than the built in Administrator but with the same account type, Administrators.
