Microsoft Issues Patches for 90 Flaws, Including 10 Critical Zero-Day Exploits

Windows 11 machines remain open to downgrade attacks, where attackers can abuse the Windows Update process to revive a patched driver signature enforcement (DSE) bypass.

A new attack technique could be used to bypass Microsoft's Driver Signature Enforcement (DSE) on fully patched Windows systems, leading to operating system (OS) downgrade attacks. "This bypass allows loading unsigned kernel drivers, enabling attackers to deploy custom rootkits that can neutralize security controls, hide processes and network activity, maintain stealth, and much more," SafeBreach

Hi there! Here’s your quick update on the latest in cybersecurity. Hackers are using new tricks to break into systems we thought were secure—like finding hidden doors in locked houses. But the good news? Security experts are fighting back with smarter tools to keep data safe. Some big companies were hit with attacks, while others fixed their vulnerabilities just in time. It's a constant battle.

The "Code-on-Toast" supply chain cyberattacks by APT37 delivered data-stealing malware to users in South Korea who had enabled Toast pop-up ads.

The shift to a distributed work model has exposed organizations to new threats, and a low but continuing stream of printer-related vulnerabilities isn't helping.

The North Korean threat actor known as ScarCruft has been linked to the zero-day exploitation of a now-patched security flaw in Windows to infect devices with malware known as RokRAT. The vulnerability in question is CVE-2024-38178 (CVSS score: 7.5), a memory corruption bug in the Scripting Engine that could result in remote code execution when using the Edge browser in Internet Explorer Mode.

Microsoft Office 2019 MSO build 1808 (16.0.10411.20011) and Microsoft 365 MSO version 2403 build 16.0.17425.20176 suffer from an NTLMv2 hash disclosure vulnerability.

A recently patched security flaw in Google Chrome and other Chromium web browsers was exploited as a zero-day by North Korean actors in a campaign designed to deliver the FudModule rootkit. The development is indicative of the persistent efforts made by the nation-state adversary, which had made a habit of incorporating rafts of Windows zero-day exploits into its arsenal in recent months.

It’s not unusual for a threat actor to exaggerate the extent of a hack or breach to drum up interest, and hopefully, the eventual purchase or ransom price.

A newly patched security flaw in Microsoft Windows was exploited as a zero-day by Lazarus Group, a prolific state-sponsored actor affiliated with North Korea. The security vulnerability, tracked as CVE-2024-38193 (CVSS score: 7.8), has been described as a privilege escalation bug in the Windows Ancillary Function Driver (AFD.sys) for WinSock. "An attacker who successfully exploited this

Voting Village co-founder Harri Hursti told Politico the list of vulnerabilities ran “multiple pages.”

CVE-2024-6768 is a vulnerability in the Common Log File System (CLFS.sys) driver of Windows, caused by improper validation of specified quantities in input data. This flaw leads to an unrecoverable inconsistency, triggering the KeBugCheckEx function and resulting in a Blue Screen of Death (BSoD). The issue affects all versions of Windows 10 and Windows 11, Windows Server 2016, Server 2019 and Server 2022 despite having all updates applied. This Proof of Concept (PoC) shows that by crafting specific values within a .BLF file, an unprivileged user can induce a system crash.

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.

The most serious of the issues included in August’s Patch Tuesday is CVE-2024-38063, a remote code execution vulnerability in Windows TCP/IP.

Microsoft said it is developing security updates to address two loopholes that it said could be abused to stage downgrade attacks against the Windows update architecture and replace current versions of the operating system files with older versions. The vulnerabilities are listed below - CVE-2024-38202 (CVSS score: 7.3) - Windows Update Stack Elevation of Privilege Vulnerability CVE-2024-21302

The good news: Only organizations far behind on standard Windows patching have anything to worry about.

A now-patched security flaw in the Microsoft Defender SmartScreen has been exploited as part of a new campaign designed to deliver information stealers such as ACR Stealer, Lumma, and Meduza. Fortinet FortiGuard Labs said it detected the stealer campaign targeting Spain, Thailand, and the U.S. using booby-trapped files that exploit CVE-2024-21412 (CVSS score: 8.1). The high-severity

Microsoft patched a record number of 147 new CVEs this month, though only three are rated "Critical."

If only Patch Tuesdays came around infrequently -- like total solar eclipse rare -- instead of just creeping up on us each month like The Man in the Moon. Although to be fair, it would be tough for Microsoft to eclipse the number of vulnerabilities fixed in this month's patch batch -- a record 147 flaws in Windows and related software.
