Hello everyone! This episode will be about Microsoft Patch Tuesday for November 2022, including vulnerabilities that were added between October and November Patch Tuesdays. As usual, I use my open source Vulristics project to create the report.

The most important news of this Patch Tuesday was a release of patches for ProxyNotShell Remote Code Execution – Microsoft Exchange (CVE-2022-41040, CVE-2022-41082) mentioned in the previous episode. These vulnerabilities became public on September 28, and updates for this vulnerability did not appear until November 8. Microsoft could have acted more quickly. But it’s good that the problem with these actively exploited vulnerabilities is finally solved.

But besides ProxyNotShell, this November Patch Tuesday had a lot of interesting vulnerabilities. Let’s take a look.

Hello everyone! Let’s take a look at Microsoft’s September Patch Tuesday. This time it is quite compact. There were 63 CVEs released on Patch Tuesday day. If we add the vulnerabilities released between August and September Patch Tuesdays (as usual, they were in Microsoft Edge), the final number is 90. Much less than usual.

Vulristics Vulnerability Score, Automated Data Collection and Microsoft Patch Tuesdays Q4 2020

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.

Vulristics Vulnerability Scores, automated data collection and Microsoft Patch Tuesday Q4 2020

Patch Tuesdays Automated Data Collection

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.
