Vulnerability appears with NVT references instead of human friendly / After upgrade: Scans showing no/0 results



Dear all,

I have recently migrated my previous Openvas-8 to Openvas-9 and I have some issues with the vulnerability results of existing tasks. Openvas-9 is running on linux mint 19 64bits.

With openvas-8; vulnerabilities found appears with their friendly name, as expected, both on the GSA console and in the csv reports.
With openvas-9; many vulnerabilities (but not all) appears with their NVT references (eg; []), both on GSA and in the csv reports.

The tasks have been previously ran under openvas-8 environment; then the database was migrated to openvas-9 where the problem is. The tasks were not restarted on the new environment as I’m currently in testing mode.

I have flushed my plugins/scap-data/cert-data directories and refreshed all the feeds but same results. Any idea where this issue comes from ?

Thanks !

After upgrade: Scans showing no/0 results

Hi, when choosing the category for a topic please try to have a look at the category description for each category first:

The current used category is/was (Description: About the Community Edition (GCE) category) which is about the downloadable ready-to use virtual machine.

Based on your posted issue it sees you have an own installation either build from source or installed via 3rdparty repositories. For such installations the (Description: About the Source Edition (GSE) category) needs to be chosen.

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.


A post was split to a new topic: After upgrade: Scans showing no/0 results


Thanks for moving my post to the correct list. I have just tested to perform a new scan on my local network with openvas-9, and surprisingly there is 0 results. The scan seems to perform OK, but I find very very suspicious that nothing at all is reported, as if all hosts were dead. There should be a problem in my installation with my feeds.

I’ve launched the openvas setup script with --v9 but there is no error. Where else should I check ?



i have split this new question not related to the plain OID shown described in your initial thread into a new topic.

For your new question have a look at the topic below for some hints if your scans are showing no results.


I’ve checked all of this and that’s not my case. I have many hosts responding to ping on my LAN, so even that simple test doesn’t work. I have nmap installed in the system path. And if I link this issue to the fact that old scan results shows NVT instead of vulnerability names, then I really believe it is linked with my feeds.


I actually found out the root cause of this issue. Going into Configuration > Scan Configs shows all scan configs with 0 NVT. Isn’t this supposed to be configured by default ? Is it overwritten when importing a tasks.db file from a previous installation ?




so it seems the initial issue might be the root cause for the scans showing no results. Based on this i have merged both topics again.


I finally found the root cause of this. NVT cache needed to be updated. openvasmd --update did the trick.
