Microsoft’s latest security updates for Patch Tuesday in February 2024 address a total of 73 vulnerabilities. Among these, five are classified as critical, including two zero-day vulnerabilities (CVE-2024-21351 and CVE-2024-21412), with thirty vulnerabilities linked to remote code execution. The utilization of vulnerability management tools is vital for identifying critical vulnerabilities and effectively addressing them.

The security update for February covers Microsoft Windows, Exchange Server, Microsoft Dynamics, Office, .NET, Microsoft WDAC OLE DB provider for SQL, Azure, Microsoft Edge (Chromium-based), Windows Kernel, and more

Zero Day Vulnerabilities

CVE-2024-21351 – Windows SmartScreen Security Feature Bypass Vulnerability. This vulnerability was actively exploited, enabling attackers to bypass SmartScreen security checks. To exploit this vulnerability, an unauthorized attacker would need to send the user a malicious file and persuade them to open it. Successful exploitation of this vulnerability could allow the attacker to circumvent the SmartScreen user experience.

CVE-2024-21412 – Internet Shortcut Files Security Feature Bypass Vulnerability. This vulnerability could bypass Mark of the Web (MoTW) warnings in Windows. Mark of the Web (MOTW) is a security feature by Microsoft aimed at preventing the download or opening of malicious files and attachments. An unauthorized attacker could send a targeted user a specially crafted file intended to bypass displayed security checks. However, the attacker lacks the ability to compel a user to view the attacker-controlled content directly. Instead, they would need to convince the user to take action by clicking on the file link.
