Summary

Windows SmartScreen Security Feature Bypass Vulnerability. This vulnerability has a high impact on confidentiality, integrity, and availability. It requires user interaction and can be exploited through a network-based attack vector. The attack complexity is low, and no privileges are required to exploit it.

Impact

If successfully exploited, this vulnerability could lead to a bypass of Windows SmartScreen security features. This could potentially allow attackers to execute malicious code or content that would normally be blocked by SmartScreen. Given the high impact on confidentiality, integrity, and availability, successful exploitation could result in unauthorized access to sensitive information, modification of system files or data, and potential disruption of system services.

Exploitation

There is no evidence that a public proof-of-concept exists. There is no evidence of proof of exploitation at the moment.

Patch

A patch is available. Microsoft has released an official fix for this vulnerability as of August 13, 2024.

Mitigation

1. Apply the official patch released by Microsoft as soon as possible. 2. Ensure all Windows systems are updated to the latest version that includes this security fix. 3. Implement additional security measures such as network segmentation and robust access controls. 4. Educate users about the risks of interacting with suspicious content or links, as this vulnerability requires user interaction. 5. Monitor systems for any unusual activity that could indicate exploitation attempts. 6. Consider implementing additional security software or tools that can compensate for SmartScreen bypasses until the patch is applied.

VERT Threat Alert: August 2024 Patch Tuesday Analysis
While updates for CVE-2024-38200 were released as part of the August Patch Tuesday drop, Microsoft had already enabled a fix for this issue on July 30, meaning that all users of supported versions of Office were protected. This vulnerability, a privilege escalation in the Windows Kernel, requires that the attacker win a race condition to successfully exploit it.

Microsoft’s August Security Update on High-Risk Vulnerabilities in Multiple Products - Security Boulevard
On August 14, NSFOCUS CERT detected that Microsoft released a security update patch for August, which fixed 90 security issues involving widely used products such as Windows, Microsoft Office, Visual Studio and Azure, including high-risk vulnerabilities such as privilege escalation and remote code execution. Due to an error in the Windows Power Dependency Coordinator after release, local attackers authenticated by ordinary users can exploit this vulnerability by running special programs to obtain SYSTEM permissions of the target system.

August Patch Tuesday goes big – Sophos News
(It should be noted that one issue patched in June, CVE-2024-38213, is under active attack in the wild – a good argument for applying patches as soon as possible after release.) Microsoft also took pains this month to flag three other CVEs for which fixes have already gone out, but that are included in Patch Tuesday information for transparency’s sake; we list those in Appendix D as well. However, with over two dozen advisories, a number of “informational” notices concerning material released in June and July, two high-profile issues for which the fixes are still a work in progress, and over 85 Linux-related CVEs covered in the release, administrators may find their patch prioritization especially complex this month.
