March In the Trend of VM (#25): once again, vulnerabilities are only in Microsoft products

March “In the Trend of VM” (#25): once again, vulnerabilities are only in Microsoft products. I present the traditional monthly roundup of trending vulnerabilities according to Positive Technologies. As in February, it turned out to be quite compact and focused on a single vendor.

🗞 Post on Habr (rus)
🗒 Digest on the PT website (rus)

All four vulnerabilities are from the February Microsoft Patch Tuesday, and all are actively being exploited in the wild:

🔻 RCE – Windows Shell (CVE-2026-21510)
🔻 RCE – Microsoft Word (CVE-2026-21514)

💬 Microsoft classified the two vulnerabilities above as Security Feature Bypass, but in fact, they are Remote Code Execution.

🔻 EoP – Windows Remote Desktop Services (CVE-2026-21533)
🔻 EoP – Desktop Window Manager (CVE-2026-21519)

🟥 The full list of trending vulnerabilities can be found on the portal

About Elevation of Privilege – Windows RDS (CVE-2026-21533) vulnerability

About Elevation of Privilege - Windows RDS (CVE-2026-21533) vulnerability

About Elevation of Privilege – Windows RDS (CVE-2026-21533) vulnerability. The vulnerability is from the February Microsoft Patch Tuesday. Remote Desktop Services (RDS) is a component of Microsoft Windows that allows a user to initiate and control an interactive session on a remote computer or virtual machine over a network connection using the Remote Desktop Protocol (RDP). Improper Privilege Management (CWE-269) in Windows Remote Desktop allows a local attacker to gain SYSTEM privileges. According to CrowdStrike, the exploit binary modifies a service configuration key, allowing the attacker to elevate privileges and “add a new user to the Administrator group”.

👾 Microsoft reports exploitation of the vulnerability in the wild. The vulnerability has been listed in the CISA KEV since February 10.

🛠 No public exploits are available yet, but there are reports of the exploit being advertised for sale for $220,000 on a dark forum.

What has become known about the Elevation of Privilege – Windows Common Log File System Driver (CVE-2024-49138) vulnerability from the December Microsoft Patch Tuesday a month later?

What has become known about the Elevation of Privilege - Windows Common Log File System Driver (CVE-2024-49138) vulnerability from the December Microsoft Patch Tuesday a month later?

What has become known about the Elevation of Privilege – Windows Common Log File System Driver (CVE-2024-49138) vulnerability from the December Microsoft Patch Tuesday a month later? Almost nothing. 🙄 This is a vulnerability in a standard Windows component, available in all versions starting with Windows Server 2003 R2. Its description is typical for EoP in Windows: if successfully exploited, a local attacker can gain SYSTEM privileges. The cause of the vulnerability is Heap-based Buffer Overflow.

Microsoft has labeled the vulnerability as being exploited in the wild, but has not provided information on where the vulnerability was being exploited or how widespread the attacks were.

The vulnerability was reported by CrowdStrike’s Advanced Research Team. But neither they nor other researchers have provided technical details yet. 🤷‍♂️ And there are no exploits yet either.

So install the December Microsoft security updates and let’s wait for news! 😉

No Boot – No Hacker!

No Boot – No Hacker! Updated track. It seems that the case with the CrowdStrike BSODStrike incident is coming to a logical conclusion. Why this happened is already more or less clear. All that remains is long legal battles between clients and the vendor. Therefore, I am closing this topic for myself with an updated track made in Suno. It’s in Russian, but subtitles are available on YouTube.

My position is that BSODStrike was not the problems of a specific company, but rather the problems of cloud CyberSecurity services with agents, whose architecture is vulnerable. Such services literally force customers to overtrust them. 🤷‍♂️ I don’t think it’s right to keep silent about this. We need to call for improving the security, transparency and controllability of such services.

It should be understood that this was just a small and relatively harmless failure, but someday we will see a case with a full-scale attack through a hacked cloud vendor. And, as it seems to me, at the moment, on-premise solutions have their advantages.
