I've just installed OpenVAS ... however when I checked on Feed Status, I found that OpenVAS CERT Feed is too old as shown in the screenshot below.
Too old (14 days) - Please check the automatic synchronization of your system
The solution suggested was to check automatic synchronization in the system. Unfortunately I was not sure how to do that.
I've searched around but couldn't find similar problem. So I guess posting the question here might be helpful.
OpenVAS CERT Feed Status: Please check the automatic synchronization of your system
To get updated content from the feeds you need to run the following scripts (in this order) on a daily base via e.g. cron:
greenbone-nvt-sync
greenbone-scapdata-sync
greenbone-certdata-sync
If there is any issue during the sync the scripts should give you additional info.
As of November 2019, you are not permitted to run the *-sync scripts as 'root'.
I installed openvas on a Kali system and found that I had some changes to make. Openvas must be installed as 'root' and openvas-setup is also supposed to be run as 'root'. But at the end of the process, there are artifacts that have root ownership and read-only attributes for everyone else which get in the way of the *-sync scripts running.
Until they sort out the installation procedures and instructions, I would recommend doing the following (after install and openvas-setup).
No need to do the chown for both the users and groups when you can do it in a single command.
