Vulners NASL Plugin Feeds for OpenVAS 9

As I already wrote earlier, you can easily add third party nasl plugins to OpenVAS. So, my friends from Vulners.com realised generation of NASL plugins for OpenVAS using own security content. I’ve tested it for scanning CentOS 7 host. And it works =)

Let’s see the whole process.

Downloading and analyzing NVD CVE feed

In previous post “New National Vulnerability Database visualizations and feeds” I mentioned JSON NVD feed.

Let’s see what data it contains, how to download and analyse it. First of all, we need to download all files with CVEs from NVD database and save them to some directory.

Unfortunately, there is no way to download all the content at once. Only one year archives. We need to get urls first. Url looks like this: https://static.nvd.nist.gov/feeds/json/cve/1.0/nvdcve-1.0-2017.json.zip. Then we will download them all.

Recently, the National Institute of Standards and Technology (NIST) introduced a new version of National Vulnerability Database (NVD) website.

What’s inside Vulners.com database and when were security objects updated last time

As I already wrote earlier, the main advantage of Vulners.com, in my opinion, is openness. An open system allows you to look under the hood, make sure that everything works fine and ask developers uncomfortable questions why there were no updates for a long time for some types of security objects.

You can do this by using the https://vulners.com/api/v3/search/stats/ request, that I already mentioned in “Downloading entire Vulners.com database in 5 minutes

First of all, let’s look at the security objects. This will give us an understanding of Vulners.com basis.

Downloading entire Vulners.com database in 5 minutes

Today I once again would like to talk about Vulners.com and why, in my opinion, it is the best vulnerability database that exist nowadays and a real game-changer.

The main thing is transparency. Using Vulners you not only can search for security content (see “Vulners – Google for hacker“), but download freely all available content from the database for your own offline analysis. And more than this, you can even see how Vulners actually works and evaluate how fresh and full the content is.

Why you may need to download full security content database? For example, you may want to create something like vulnerability quadrants.
