Hello everyone! This episode will be about Microsoft Patch Tuesday for May 2022. Sorry for the delay, this month has been quite intense. As usual, I’m using my Vulristics project and going through not only the vulnerabilities that were presented on May 10th, but all the MS vulnerabilities presented by Microsoft since the previous Patch Tuesday, April 12th.

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.

Malicious Open Source: the cost of using someone else’s code

Hello everyone! This video was recorded for the VMconf 22 Vulnerability Management conference, vmconf.pw. I will be talking about malicious open source and the cost of using someone else’s code.

To be honest, at the beginning of the year I did not plan to talk about these things. But life changes rapidly and unpredictably, so it becomes impossible not to talk about this.

Microsoft Patch Tuesday April 2022 and custom CVE comments sources in Vulristics

Hello everyone! This episode will be about Microsoft Patch Tuesday for April 2022 and new improvements in my Vulristics project. I decided to add more comment sources. Because it’s not just Tenable, Qualys, Rapid7 and ZDI make Microsoft Patch Tuesday reviews, but also other security companies and bloggers.

You can see them in my automated security news telegram channel avleonovnews after every second Tuesday of the month. So, now you can add any links with CVE comments to Vulristics.

CISO Forum 2022: the first major Russian security conference in the New Reality

Hello everyone! After a two-year break, I took part in Moscow CISO Forum 2022 with a small talk “Malicious open source: the cost of using someone else’s code”.

Alternative video link (for Russia): https://vk.com/video-149273431_456239084

CISO Forum is the first major Russian conference since the beginning of The New Reality of Information Security (TNRoIS). My presentation was just on this topic. How malicious commits in open source projects change development and operations processes. I will make a separate video about this (upd. added Malicious Open Source: the cost of using someone else’s code). In this episode, I would like to tell you a little about the conference itself.

Gitlab OmniAuth Static Passwords and stored XSS

Hello everyone! In this episode, let’s take a look at the latest vulnerabilities in Gitlab. On March 31, the Critical Security Release for GitLab Community Edition (CE) and Enterprise Edition (EE) was released. GitLab recommends that all installations running a version affected by the issues described in the bulletin are upgraded to the latest version as soon as possible.

Unfortunately, Gitlab, as well as some other Western companies, is currently hostile to the country where I live and work. So their calls to immediately install updates now have additional connotations. If Gitlab is so clearly politically motivated that even the logo on their site has been recolored in a certain way, then what else can be expected from their updates? Backdoors? Malicious functionality that wipes data? Quite possible. IMHO, when companies are so willing to mix geopolitical messages and business, it exposes them as unreliable vendors that should be avoided.

But let’s get back to vulnerabilities. There are 17 CVEs in the bulletin. We will start with the most critical one.

Spring4Shell, Spring Cloud Function RCE and Spring Cloud Gateway Code Injection

Hello everyone! This episode will be about last week’s high-profile vulnerabilities in Spring. Let’s figure out what happened.

Of course, it’s amazing how fragmented the software development world has become. Now there are so many technologies, programming languages, libraries and frameworks! It becomes very difficult to keep them all in sight. Especially if it’s not the stack you use every day. Entropy keeps growing every year. Programmers are relying more and more on off-the-shelf libraries and frameworks, even where it may not be fully justified. And vulnerabilities in these off-the-shelf components lead to huge problems. So it was in the case of a very critical Log4Shell vulnerability, so it may be in the case of Spring vulnerabilities.

Spring is a set of products that are used for Java development. They are developed and maintained by VMware. The main one is Spring Framework. But there are a lot of them, at least 21 on the website. And because Spring belongs to VMware, you can find a description of the vulnerabilities on the VMware Tanzu website. VMware Tanzu is a suite of products that helps users run and manage multiple Kubernetes (K8S) clusters across public and private “clouds”. Spring is apparently also part of this suite and therefore Spring vulnerabilities are published there. Let’s look at the 3 most serious vulnerabilities published in the last month.
