Vulners Web Vulnerability Scanner plugin for Google Chrome v. 2.0

Vulners Team released today the second version of their Web Vulnerability Scanning plugin for Google Chrome browser. You can read my description of the version 1.0 at “Vulners.com vulnerability detection plugins for Burp Suite and Google Chrome“.

Vulners web vulnerability scanner v.2.0

Killing feature of Vulners web scanner v. 2.0 is that you can now see all vulnerabilities on all scanned sites in a single window. You don’t need to checks all Google Chrome tabs manually.

Moreover, if some sites make request to other servers, for example googleapis.com, these servers will be checked automatically.

The plugin was fully refactored and now it is React driven. It works faster, analysis more data sources and detects vulnerabilities more accurately.

Kenna Security: Analyzing Vulnerability Scan data

I’ve been following Kenna Security (before 2015 Risk I/O) for a pretty long time. Mainly, because they do the things I do on a daily basis: analyse various vulnerability scan results and feeds, and prioritize detected vulnerabilities for further mitigation. The only difference is that my scripts and reports are highly specific for my employer’s infrastructure and needs. And guys from Kenna team make a standardized scalable cloud solution that should be suitable for everyone.

I think their niche is really great. They do not compete directly with Vulnerability Management vendors. They can be partners with any of them, bringing additional features to the customers. Perfect win-win combination. That’s why Kenna speakers regularly participate in joint webinars with VM vendors.

I couldn’t lose a great opportunity to see Kenna Security service in action. 😉

In this post I will try to make a very brief review of Kenna functionality and formulate pros and cons of the solution.

When you submit trial request at https://www.eu.kennasecurity.com/signup (or https://app.kennasecurity.com/signup if you are not in Europe) you will get a link to your company account:


The login screen will look like this:

CWEs in NVD CVE feed: analysis and complaints

As you probably know, one of the ways to describe the nature of some software vulnerability is to provide corresponding CWE (Common Weakness Enumeration) ids. Let’s see the CWE links in NVD CVE base.


I have already wrote earlier how to deal with NVD feed using python in “Downloading and analyzing NVD CVE feed“. You can easily get CWEs ids iterating over cve_dict['CVE_Items'].

Downloading and analyzing NVD CVE feed

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

NVD JSON feed parse python

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.

nvd feed json download

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.

New National Vulnerability Database visualizations and feeds

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

I will not say that I liked this redesign:

IMHO, old website with US flag was much prettier and useful:

But the very fact that the site is developing, I really like very much. Let’s see what’s new there.
