Microsoft is beginning to add CVEs to address security flaws in its cloud services

Microsoft is beginning to add CVEs to address security flaws in its cloud services

Microsoft is beginning to add CVEs to address security flaws in its cloud services. It’s not as straightforward. Assume a cloud CRM has a vulnerability. The vendor instantly corrected it for everyone, and clients didn’t need to take any action. What good is it to issue a CVE for this? 🤔

But Microsoft believes it’s required for greater transparency, and the new rules require CNAs (CVE Numbering Authorities) to add vulnerabilities that could cause significant harm, regardless of whether customers have to take action to fix the vulnerabilities or not. 🤷‍♂️

Microsoft promises to mark such vulnerabilities, such as CVE-2024-35260 “CVE requires no customer action to resolve”. There will be a special tag in CVEorg as well.

Whether or not it is necessary to register cloud service vulnerabilities as CVE is a controversial issue. But it is a fact that, due to this practice, the number of identifiers in CVEorg/NVD will grow much faster. 🤷‍♂️

An idea worth a million Hamster coins

An idea worth a million Hamster coins

An idea worth a million Hamster coins. 🐹😅 Website/app to tap on CVEs. But it will make sense to tap not on all CVEs, but only on those that should have a confirmed exploit or sign of exploitation in the wild within the next week.

🪙 When such a sign or exploit does appear, distribute coins to those who have been tapping on this vulnerability for the last week. In proportion to the number of taps, the criticality of the vulnerability, etc.

📈 And based on the analysis of these taps, it will be possible to make forecasts on the exploitability of vulnerabilities. With the help of AI, of course.

I am sure that this will work much better than EPSS and social network fortune tellers. 😅

November 2023 – January 2024: New Vulristics Features, 3 Months of Microsoft Patch Tuesdays and Linux Patch Wednesdays, Year 2023 in Review

November 2023 – January 2024: New Vulristics Features, 3 Months of Microsoft Patch Tuesdays and Linux Patch Wednesdays, Year 2023 in Review. Hello everyone! It has been 3 months since the last episode. I spent most of this time improving my Vulristics project. So in this episode, let’s take a look at what’s been done.

Alternative video link (for Russia): https://vk.com/video-149273431_456239139

Also, let’s take a look at the Microsoft Patch Tuesdays vulnerabilities, Linux Patch Wednesdays vulnerabilities and some other interesting vulnerabilities that have been released or updated in the last 3 months. Finally, I’d like to end this episode with a reflection on how my 2023 went and what I’d like to do in 2024.

August 2023: GitHub PoCs, Vulristics, Qualys First-Party, Tenable ExposureAI, SC Awards and Rapid7, Anglo-Saxon list, MS Patch Tuesday, WinRAR, Juniper

August 2023: GitHub PoCs, Vulristics, Qualys First-Party, Tenable ExposureAI, SC Awards and Rapid7, Anglo-Saxon list, MS Patch Tuesday, WinRAR, Juniper. Hello everyone! This month I decided NOT to make an episode completely dedicated to Microsoft Patch Tuesday. Instead, this episode will be an answer to the question of how my Vulnerability Management month went. A retrospection of some kind.

How Debian OVAL content is structured

How Debian OVAL content is structured. Hello everyone! As we saw in the last episode, the results of vulnerability detection for one host produced by two different APIs can vary greatly. Therefore, in order to find out the truth, it is necessary to understand what vulnerability data is provided by the Linux distribution vendor and how this data is structured.

Alternative video link (for Russia): https://vk.com/video-149273431_456239114

Why is it important to do this? Because using data from a Linux distribution vendor, we can ask vulnerability detection API vendors questions: why are you detecting in a different way than described in this data? And then we will understand what caused the difference. And we will either adjust the API for vulnerability detection, or we will adjust the content of the Linux distribution vendor. Either way, it will be a success! In any case, the transparency of the vulnerability detection process will increase.

Last time we looked at vulnerabilities for Debian host and Debian Docker base image. So let’s continue with Debian. In particular, with the official Debian OVAL (Open Vulnerability and Assessment Language) content.

Debian OVAL content can be downloaded from the https://debian.org/security/oval/ website. For Debian 11.6 it will be https://debian.org/security/oval/oval-definitions-bullseye.xml (~48M).

Vulristics May 2022 Update: CVSS redefinitions and bulk adding Microsoft products from MS CVE data

Vulristics May 2022 Update: CVSS redefinitions and bulk adding Microsoft products from MS CVE data. Hello everyone! In this episode, I want to talk about the latest updates to my open source vulnerability prioritization project Vulristics.

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.

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

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.

Alternative video link (for Russia): https://vk.com/video-149273431_456239085

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.
