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.

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.

Vulnerability Management news and publications #2

Hello everyone! This is the second episode of Vulnerability Management news and publications. In fact, this is a collection of my posts from the avleonovcom and avleonovrus telegram channels. Therefore, if you want to read them earlier, subscribe to these channels.

The main idea of ​​this episode. Microsoft is a biased company. In fact, they should now be perceived as another US agency. Does this mean that we need to forget about Microsoft and stop tracking what they do? No, it doesn’t. They do a lot of interesting things that can at least be researched and copied. Does this mean that we need to stop using Microsoft products? In some locations (you know which ones) for sure, in some we can continue to use such products if it is reasonable, but it’s necessary to have a plan B. And this does not only apply to Microsoft. So, it’s time for a flexible approaches. Here we do it this way, there we do it differently. It seems that rather severe fragmentation of the IT market is a long-term trend and it’s necessary to adapt to it.

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. 🙂
