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. This time there were only 3 vulnerabilities used in attacks or with a public exploit. And only one of them is more or less relevant.

It’s been a long time since we’ve had such tiny Patch Tuesday. 57 CVEs, including CVEs appeared during the month. And only 38 without them! 😄

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.

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.

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. 🙂

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.
