Microsoft Patch Tuesday September 2020: Zerologon and other exploits, RCEs in SharePoint and Exchange

I would like to start this post by talking about Microsoft vulnerabilities, which recently turned out to be much more serious than it seemed at first glance.

Older Vulnerabilities with exploits

“Zerologon” Netlogon RCE (CVE-2020-1472)

One of them is, of course, the Netlogon vulnerability from the August 2020 Patch Tuesday. It’s called “Zerologon”. I would not say that Vulnerability Management vendors completely ignored it. But none of them (well, maybe only ZDI) emphasized in their reports that this vulnerability would be a real disaster.

Microsoft Patch Tuesday May 2020: comments from VM vendors, promising stuff for phishing, troubles with SharePoint and lulz with Visual Studio

This will be my third Microsoft Patch Tuesday report in video and audio format. And for the third time in a row, Microsoft has addressed over a hundred vulnerabilities. With my Microsoft Patch Tuesday parser, it was possible to generate a report almost on the same day. But, of course, it takes much more time to describe the vulnerabilities manually.

Microsoft Patch Tuesday May 2020
  • All vulnerabilities: 111
  • Critical: 16
  • Important: 95
  • Moderate: 0
  • Low: 0

Last time I complained that different VM vendors release completely different reports for Microsoft Patch Tuesday. This time I decided that it’s not a bug, but a feature. I upgraded my script to not only show vulnerabilities, but also show how these vulnerabilities were mentioned in the reports of various VM vendors (Tenable, Qualys, Rapid7 and ZDI). In my opinion, it seems pretty useful.

Microsoft Patch Tuesday April 2020: my classification script, confusing RCE in Adobe Type Manager and updates for older vulnerabilities

Easiest task ever?

Making the reviews of Microsoft Patch Tuesday vulnerabilities should be an easy task. All vulnerability data is publicly available. Even better, dozens of reviews have already been written. Just read them, combine and post. Right?

Microsoft Patch Tuesday April 2020: my classification script, confusing RCE in Adobe Type Manager and updates for older vulnerabilities

Not really. In fact it is quite boring and annoying. It may be fun to write about vulnerabilities that were already used in some real attacks. But this is a very small part of all vulnerabilities. What about more than a hundred others? They are like “some vulnerability in some component may be used in some attack (or may be not)”. If you describe each of them, no one will read or listen this.

You must choose what to highlight. And when I am reading the reports from Tenable, Qualys and ZDI, I see that they choose very different groups of vulnerabilities, pretty much randomly.

My classification script

That’s why I created a script that takes Patch Tuesday CVE data from microsoft.com and visualizes it giving me helicopter view on what can be interesting there. With nice grouping by vulnerability type and product, with custom icons for vulnerability types, coloring based on severity, etc.

Vulnerability Management Product Comparisons (October 2019)

Here I combined two posts [1.2] from my telegram channel about comparisons of Vulnerability Management products that were recently published in October 2019. One of them was more marketing, published by Forrester, the other was more technical and published by Principled Technologies.

Vulnerability Management Product Comparisons (October 2019)

I had some questions for both of them. It’s also great that the Forrester report made Qualys, Tenable and Rapid7 leaders and Principled Technologies reviewed the Knowledge Bases of the same three vendors.

Let’s start with Forrester.

Asset Inventory for Internal Network: problems with Active Scanning and advantages of Splunk

In the previous post, I was writing about Asset Inventory and Vulnerability Scanning on the Network Perimeter. Now it’s time to write about the Internal Network.

Typical IT-infrastructure of a large organization

I see a typical IT-infrastructure of a large organization as monstrous favela, like Kowloon Walled City in Hong Kong. At the beginning it was probably wisely designed, but for years it  was highly effected by spontaneous development processes in various projects as well as multiple acquisitions. And now very few people in the organization really understand how it all works and who owns each peace.

There is a common belief that we can use Active Network Scanning for Asset Inventory in the organization. Currently, I’m not a big fan of this approach, and I will try to explain here the disadvantages of this method and mention some alternatives.

Qualys Security Conference Virtual 2018. New Agents, Patch Management and Free Services

Today I attended a very interesting online event – Qualys Security Conference Virtual 2018. It consisted of 11 webinars, began at 18:00 and will end at 03:45 Moscow time. Not the most convenient timing for Russia, but it was worth it. 🙂

Qualys Security Conference 2018

Last time I was at offline QSC event in 2016, so for me it was especially interesting to learn about the new features of Qualys platform.

PHDays8: Digital Bet and thousands tons of verbal ore

It’s time to write about Positive Hack Days 8: Digital Bet conference, which was held May 15-16 at the Moscow World Trade Center. It was the main Russian Information Security event of the first half of 2018. More than 4 thousand people attended! More than 50 reports, master classes and round tables held in 7 parallel streams. And, of course, impressive CTF contest for security experts and hackers with an fully-functioning model of the city.

Hack Days 8: Digital Bet

I was very pleased that there was a separate section dedicated to Vulnerability Management. Something similar happened only at ISACA meetup last year. But here we had an event for several thousand people!

The session was held in Fast Track format: 20 minutes for the presentation and questions. I was the first to speak. My report was called “Vulnerability Databases: sifting thousands tons of verbal ore”. Here is the video:

And here’s a link to the version with only Russian sound track.
