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. And this is the first Patch Tuesday report since I added EPSS support to Vulristics. 😉

Compared to March, Microsoft Patch Tuesday for April 2023 is kind of weak. 🙄

EPSS v3

The third iteration of the Exploit Prediction Scoring System (EPSS) was released in March. It is stated that EPSS has become 82% better. There is a pretty cool and detailed article about the changes. For example, EPSS Team began to analyze not 16 parameters of vulnerabilities, but 1164. I have a suspicion that most of these properties are vendor labels, as in the table.

But trying to figure out how it actually works is not very promising. After all, this is the output of some neural network. So there is no algorithm there. In terms of complexity and incomprehensibility, this is already similar to Tenable VPR. But the fact that EPSS is available for free redeems everything. 😇 By the way, the article mentions Tenable VPR and other commercial scores and criticizes them for their proprietary nature, public inaccessibility, and the fact that these scores are partly based on expert opinion, and not just on data.

This month I decided to change the format a bit. Now I share my impression of Microsoft Patch Tuesday on the same Patch Tuesday day in my main telegram channel avleonovcom and my second russian telegram channel avleonovrus. You can also find a draft of the Vulristics report there. So please subscribe. And the full blog post/video is published with a delay. And, in fact, this is it.

Microsoft Patch Tuesday September 2022: CLFS Driver EoP, IP packet causes RCE, Windows DNS Server DoS, Spectre-BHB

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.
