Microsoft on Tuesday shipped fixes to address a total of 90 security flaws, including 10 zero-days, of which six have come under active exploitation in the wild.
Of the 90 bugs, seven are rated Critical, 79 are rated Important, and one is rated Moderate in severity. This is also in addition to 36 vulnerabilities that the tech giant resolved in its Edge browser since last month.

Microsoft today released updates to fix at least 90 security vulnerabilities in Windows and related software, including a whopping six zero-day flaws that are already being actively exploited by attackers.

This month’s bundle of update joy from Redmond includes patches for security holes in Office, .NET, Visual Studio, Azure, Co-Pilot, Microsoft Dynamics, Teams, Secure Boot, and of course Windows itself. Of the six zero-day weaknesses Microsoft addressed this month, half are local privilege escalation vulnerabilities — meaning they are primarily useful for attackers when combined with other flaws or access.

CVE-2024-38106, CVE-2024-38107 and CVE-2024-38193 all allow an attacker to gain SYSTEM level privileges on a vulnerable machine, although the vulnerabilities reside in different parts of the Windows operating system.

Microsoft’s advisories include little information about the last two privilege escalation flaws, other than to note they are being actively exploited. Microsoft says CVE-2024-38106 exists in the Windows Kernel and is being actively exploited, but that it has a high “attack complexity,” meaning it can be tricky for malware or miscreants to exploit reliably.

“Microsoft lists exploit complexity as high due to the attacker needing to win a race condition,” Trend Micro’s ZeroDay Initiative (ZDI) noted. “However, some races are easier to run than others. It’s times like this where the CVSS can be misleading. Race conditions do lead to complexity high in the CVSS score, but with attacks in the wild, it’s clear this bug is readily exploitable.”

Another zero-day this month is CVE-2024-38178, a remote code execution flaw that exists when the built-in Windows Edge browser is operating in “Internet Explorer Mode.” IE mode is not on by default in Edge, but it can be enabled to work with older websites or applications that aren’t supported by modern Chromium-based browsers.

“While this is not the default mode for most users, this exploit being actively exploited suggests that there are occasions in which the attacker can set this or has identified an organization (or user) that has this configuration,” wrote Kev Breen, senior director of threat research at Immersive Labs.

CVE-2024-38213 is a zero-day flaw that allows malware to bypass the “Mark of the Web,” a security feature in Windows that marks files downloaded from the Internet as untrusted (this Windows Smartscreen feature is responsible for the “Windows protected your PC” popup that appears when opening files downloaded from the Web).

“This vulnerability is not exploitable on its own and is typically seen as part of an exploit chain, for example, modifying a malicious document or exe file to include this bypass before sending the file via email or distributing on compromised websites,” Breen said.

The final zero-day this month is CVE-2024-38189, a remote code execution flaw in Microsoft Project. However, Microsoft and multiple security firms point out that this vulnerability only works on customers who have already disabled notifications about the security risks of running VBA Macros in Microsoft Project (not the best idea, as malware has a long history of hiding within malicious Office Macros).

Separately, Adobe today released 11 security bulletins addressing at least 71 security vulnerabilities across a range of products, including Adobe Illustrator, Dimension, Photoshop, InDesign, Acrobat and Reader, Bridge, Substance 3D Stager, Commerce, InCopy, and Substance 3D Sampler/Substance 3D Designer. Adobe says it is not aware of active exploitation against any of the flaws it fixed this week.

It’s a good idea for Windows users to stay current with security updates from Microsoft, which can quickly pile up otherwise. That doesn’t mean you have to install them on Patch Tuesday each month. Indeed, waiting a day or three before updating is a sane response, given that sometimes updates go awry and usually within a few days Microsoft has fixed any issues with its patches. It’s also smart to back up your data and/or image your Windows drive before applying new updates.

For those admins responsible for maintaining larger Windows environments, it pays to keep an eye on Askwoody.com, which frequently points out when specific Microsoft updates are creating problems for a number of users.
