Microsoft has released its July 2024 Patch Tuesday security updates, addressing a total of 142 vulnerabilities, including four zero-day vulnerabilities. Notably, two of these zero-days are actively being exploited in the wild, posing significant risks to organizations using Microsoft products. Read on to learn more. 

What are the zero-day vulnerabilities mentioned in Microsoft’s July 2024 Patch Tuesday?  

The two actively exploited zero-day vulnerabilities are: 

• CVE-2024-38080: This critical vulnerability affects the Windows Hyper-V component on Windows 11 and Windows Server 2022 systems. It allows attackers to elevate their account privileges on a Windows machine, potentially granting them SYSTEM-level access. The impact of this vulnerability is severe, as it could enable the deployment of ransomware and other malicious attacks. Due to its low complexity and no user interaction requirements, it’s likely to be rapidly incorporated into exploit kits, leading to widespread exploitation. 

• CVE-2024-38112: This weakness in MSHTML, the engine behind Microsoft’s Internet Explorer, is a spoofing vulnerability that requires attackers to take additional preparatory actions to exploit the target environment. It allows an attacker to send a malicious file to a user for execution across the network. While details are scarce, it’s known to be actively exploited and requires social engineering to convince a user to execute a delivered file. 

The other two publicly disclosed zero-day vulnerabilities are: 

• CVE-2024-37985: Assigned by Intel, this vulnerability affects certain ARM-based operating systems. Microsoft has issued updates for the ARM version of Windows 11 to mitigate this issue. It could potentially allow an attacker to view heap memory from a privileged process. 

• CVE-2024-35264: An HTTP/3 vulnerability in .NET and Visual Studio that could result in remote code execution. Exploitation is less likely due to the need for an attacker to win a race condition. It has been assigned a CVSSv3 score of 8.1, indicating its high severity.
