Hello everyone! In this short episode, I want to talk about the new feature in Vulners Linux API.

Linux security bulletin publication dates are now included in scan results. Why is it useful?

A fairly common problem: we have a CVE without an available CVSS vector and score. For example, this was the case with CVE-2022-1364 Type Confusion in V8 (Chromium). This vulnerability does not exist in NVD.
Continue readingHello everyone! This episode will be about Microsoft Patch Tuesday for April 2022 and new improvements in my Vulristics project. I decided to add more comment sources. Because it’s not just Tenable, Qualys, Rapid7 and ZDI make Microsoft Patch Tuesday reviews, but also other security companies and bloggers.

You can see them in my automated security news telegram channel avleonovnews after every second Tuesday of the month. So, now you can add any links with CVE comments to Vulristics.
Continue readingHello everyone! This video was recorded for the VMconf22 Vulnerability Management conference. I want to talk about the blind spots in the knowledge bases of Vulnerability Scanners and Vulnerability Management products.
This report was presented in Russian at Tenable Security Day 2022. The video is here.
Potential customers rarely worry about the completeness of the Knowledge Base when choosing a Vulnerability Scanner. They usually trust the VM vendors’ claims of the “largest vulnerability base” and the total number of detection plugins. But in fact the completeness is very important. All high-level vulnerability prioritization features are meaningless unless the vulnerability has been reliably detected. In this presentation, I will show the examples of blindspots in the knowledge bases of vulnerability management products, try to describe the causes and what we (as customers and the community) can do about it.
Continue readingHello all! It is the second part about AM Live Vulnerability Management conference. In the first part I made the timecodes for the 2 hours video in Russian. Here I have combined all my lines into one text.
Vulnerability Management process is the opposite of the admin’s saying “If it works – don’t touch it!”. The main idea of this process is to somehow fix the vulnerabilities. How do you achieve this is not so important. Maybe you will have a nice Plan-Do-Check-Act process and strict policies. Maybe not. The main thing is that you fix vulnerabilities! And the main problem is to negotiate this regular patching with system administrators and service owners.
Continue readingHello everyone! This episode will be about Vulners Linux Audit API, which allows you to detect vulnerabilities on a Linux host knowing only the OS version and installed packages. I had a similar post about this 4 years ago, but some details have changed, so I came back to this topic.
In this episode I would like to make a status update of my Vulristics project. For those who don’t know, in this project I retrieve publicly available vulnerability data and analyze it to better understand the severity of these vulnerabilities and better prioritize them. Currently, it is mainly about Microsoft Patch Tuesday vulnerabilities, but I have plans to go further. Also in this episode I want to demonstrate the new Vulristics features on Microsoft Patch Tuesday reports for October, November and December 2020.
First of all, I dealt with the annoying collecting of the data for Microsoft Patch Tuesdays reports. Previously it took pretty long time. I had to go to Microsoft website and search for CVE IDs. After that, I had to get the comments from various Vulnerability Management vendors and researchers blogs (Tenable, Qualys, Rapid7, ZDI). I wanted this to be as much automated as possible. I have added some code to make CVE search requests on the Microsoft website for a date range (including the second Tuesday of the month). I also figured out how to make searches on the Vulnerability Management vendors blogs. So, now to get a Microsoft Patch Tuesday report it’s only necessary to set the year and month.
