I’ve got the latest NVTs (GCF) by rsync and merged into my scanner system successfully. However, the scan result is very different. Before the NVTs update, 300+ vulnerabilities could be scanned out, however, after the update, only 200- vulnerabilities be scanned out on the same scan target, and the scanned out vulnerabilities is very different.
So my question is : to use the current NVTs, is there a requirement for the update of Openvas?
BTW, I’m using a very old openvas: version 5.1.3 for Openvas Scanner, and version 7.0.3 for OpenVas Manager.
Thank you for your kind help! Any feedback from you will be greatly appreciated.
