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.

Americans can’t just release a list of “20 vulnerabilities most commonly exploited in attacks on American organizations.” They like to add geopolitics and point the finger at some country. Therefore, I leave the attack attribution mentioned in the advisory title without comment.

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.

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. 🙂
