Microsoft Patch Tuesday December 2022: SPNEGO RCE, Mark of the Web Bypass, Edge Memory Corruptions

Leave a reply

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

But let’s start with an older vulnerability. This will be another example why vulnerability prioritization is a tricky thing and you should patch everything. In the September Microsoft Patch Tuesday there was a vulnerability Information Disclosure – SPNEGO Extended Negotiation (NEGOEX) Security Mechanism (CVE-2022-37958), which was completely unnoticed by everyone. Not a single VM vendor paid attention to it in their reviews. I didn’t pay attention either.

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

Leave a reply

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.

Microsoft Patch Tuesday August 2022: DogWalk, Exchange EOPs, 13 potentially dangerous, 2 funny, 3 mysterious vulnerabilities

Leave a reply

Hello everyone! In this episode, let’s take a look at the Microsoft Patch Tuesday August 2022 vulnerabilities. I use my Vulristics vulnerability prioritization tool as usual. I take comments for vulnerabilities from Tenable, Qualys, Rapid7, ZDI and Kaspersky blog posts. Also, as usual, I take into account the vulnerabilities added between the July and August Patch Tuesdays.

There were 147 vulnerabilities. Urgent: 1, Critical: 0, High: 36, Medium: 108, Low: 2.

There was a lot of great stuff this Patch Tuesday. There was a critical exploited in the wild MSDT DogWalk vulnerability, 3 critical Exchange vulnerabilities that could be easily missed in prioritization, 13 potentially dangerous vulnerabilities, 2 funny vulnerabilities and 3 mysterious ones. Let’s take a closer look.

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

Leave a reply

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. 🙂

Vulristics May 2022 Update: CVSS redefinitions and bulk adding Microsoft products from MS CVE data

1 Reply

Hello everyone! In this episode, I want to talk about the latest updates to my open source vulnerability prioritization project Vulristics.

CVSS redefinitions

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.

Microsoft Patch Tuesday March 2022

Leave a reply

Hello everyone! I am glad to greet you from the most sanctioned country in the world. Despite all the difficulties, we carry on. I even have some time to release new episodes. This time it will be about Microsoft Patch Tuesday for March 2022.

Alternative video link (for Russia): https://vk.com/video-149273431_456239076

I do the analysis as usual with my open source tool Vulristics. You can still download it on github. I hope that github won’t block Russian repositories and accounts, but for now it looks possible. Most likely, I will just start hosting the sources of my projects on avleonov.com in this case. Or on another domain, if it gets even tougher. Stay tuned.

Microsoft Patch Tuesday February 2022

Leave a reply

Hello everyone! This episode will be about Microsoft Patch Tuesday for February 2022. I release it pretty late, because of the my previous big episode about the blindspots in the Knowledge Bases of Vulnerability Scanners. Please take a look if you haven’t seen it. Well, if you are even slightly interested in the world news, you can imagine that the end of February 2022 in Eastern Europe is not the best time to create new content on Vulnerability Management. Let’s hope that peace and tranquility will be restored soon. And also that geopolitical confrontation between the largest nuclear powers will de-escalate somehow.

But let’s get back to information security. While working on Microsoft Patch Tuesday report for February 2022, I made a lot of improvements to my open source project for vulnerability prioritization Vulristics. I want to start with them.
