As usual, I use my open source Vulristics project to analyse and prioritize vulnerabilities. I took the comments about the vulnerabilities from the Qualys, Tenable, Rapid7, ZDI Patch Tuesday reviews.

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.

Microsoft Patch Tuesday July 2022: propaganda report, CSRSS EoP, RPC RCE, Edge, Azure Site Recovery

Hello everyone! Microsoft has been acting weird lately. I mean the recent publication of a propaganda report about evil Russians and how Microsoft is involved in the conflict between countries. It wouldn’t be unusual for a US government agency, NSA or CIA to publish such a report. But when a global IT vendor, which, in theory, should be more or less neutral, does this… This is a clear signal. It’s not about business anymore.

I’ll take a closer look at this report in the next episode of the Vulnerability Management news, but for now let’s take a look at Microsoft July Patch Tuesday. Yes, the vendor is behaving strangely, but Microsoft products need to be patched. Right? At least for now. And tracking vulnerabilities is always a good thing. 🙂

Microsoft Patch Tuesday April 2022 and custom CVE comments sources in Vulristics

Hello 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.

Microsoft Patch Tuesday January 2022

Hello everyone! This episode will be about Microsoft Patch Tuesday for January 2022. Traditionally, I will use my open source Vulristics tool for analysis. This time I didn’t make any changes to how connectors work. The report generation worked correctly on the first try.

python3.8 vulristics.py --report-type "ms_patch_tuesday" --mspt-year 2022 --mspt-month "January" --rewrite-flag "True"

The only thing I have improved is the detection of types of vulnerabilities and vulnerable products. “Unknown Vulnerability Type” was for two vulnerabilities, so I added the “Elevation Of Privilege” и “Cross-Site Scripting” spelling options. I added detections for 13 products and 19 Windows components. I also corrected the method for sorting vulnerabilities with the same Vulristics score. Previously, such vulnerabilities were sorted by CVE id, now they are sorted by vulnerability type and product. This allows you to see the clusters of similar vulnerabilities.

Vulristics: Microsoft Patch Tuesdays Q1 2021
