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. 🙄

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.

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.

Security News: Exchange ProxyShell, Zoom RCE, Citrix Canceled PT Acknowledgments, Cisco No Patch Router RCEs

Security News: Exchange ProxyShell, Zoom RCE, Citrix Canceled PT Acknowledgments, Cisco No Patch Router RCEs. Hello everyone! This is a new episode with my comments on the latest Information Security news.

Exchange ProxyShell

I want to start with something about attacks on Exchange. ProxyShell is in the news, the LockFile ransomware compromised more than 2000 servers. On the other hand, there is basically nothing to say here.

ProxyShell is the name for 3 vulnerabilities. The bulletins for Remote Code Execution CVE-2021-34473 and Server Elevation of Privilege CVE-2021-34523 were released on July 13, but were fixed by April Patch Tuesday patches. Yes, it happens sometimes. The bulletin for Security Feature Bypass CVE-2021-31207 was released on May 11. Users had 4 months to install the updates. Interestingly, 2 out of 3 vulnerabilities have the property “Less likely to be exploited”. As you can see, it’s pretty useless.

Last Week’s Security news: Pegasus, SeriousSAM, Sequoia. Hello everyone! After 4 episodes of the Last Week’s Security news, I decided to change the format. I will no longer try to cover all the important news, because it takes a long time to prepare such reviews. So, from now on, I will focus only on a few news of the past week, which I subjectively consider the most interesting.

So, the last week, July 19 – July 25. In my opinion, the most interesting news was the scandal related to the iPhone Pegasus spyware and two Elevations of Privileges: SeriousSAM for Windows and Sequoia for Linux.
