Microsoft’s August 2023 Patch Tuesday Highlights

Microsoft’s August 2023 Patch Tuesday has just arrived, accompanied by critical fixes, zero-day vulnerabilities, and many other security updates. We will highlight the vulnerabilities addressed, the risks associated with the zero-day exploits, and the steps organizations can take to safeguard their systems. Leveraging insights from SOCRadar Vulnerability Intelligence, we’ll navigate the complex landscape of cybersecurity to ensure your digital defenses are fortified.

Zero-Day Vulnerabilities and Critical Fixes

This month’s Patch Tuesday addresses two zero-day vulnerabilities that have been actively exploited. The first of these vulnerabilities, identified as CVE-2023-36884, serves as a reminder of the ever-evolving threat landscape. The vulnerability involves the exploitation of Microsoft Office and its defense mechanism. Originally thought to be a remote code execution vulnerability, and was addressed in Microsoft July 2023 Patch Tuesday. However, it was later classified as a security feature bypass. This vulnerability allowed threat actors to create manipulated Office documents that circumvent security warnings, an exploit that the RomCom hacking group, now operating under the name ‘Underground.’

The other exploited vulnerability, CVE-2023-38180, targets .NET applications and Visual Studio, enabling attackers to launch Distributed Denial of Service (DDoS) attacks. While specific details regarding the exploitation remain undisclosed, its potential for widespread impact is concerning. These zero-day vulnerabilities underscore the urgency of applying updates promptly and the importance of advanced threat detection, such as SOCRadar’s Vulnerability Intelligence module, which can provide critical insights into emerging risks.

Vulnerability Landscape 

The August 2023 Patch Tuesday addresses 87 vulnerabilities, encompassing a variety of categories, including elevation of privilege, remote code execution, information disclosure, distributed denial of service, and spoofing. Six of these are classified as critical, emphasizing the need for swift action. While none of the identified vulnerabilities have been reported as actively exploited, even though the dynamic nature of cyber threats necessitates proactive measures.

A particular focus lies on vulnerabilities such as CVE-2023-35385, CVE-2023-36910, and CVE-2023-36911, which impact Microsoft Message Queuing. These remote code execution vulnerabilities highlight the importance of securing essential services that attackers could exploit to infiltrate systems.
