Summary

Microsoft DWM Core Library Elevation of Privilege Vulnerability. This is a locally exploitable vulnerability with a low attack complexity that requires low privileges and no user interaction. It has high impacts on confidentiality, integrity, and availability.

Impact

If successfully exploited, this vulnerability could allow an attacker to elevate their privileges on the affected system. The attacker could potentially gain unauthorized access to sensitive information, modify or delete data, and disrupt system availability. Given the high impact on confidentiality, integrity, and availability, this could lead to significant compromise of the affected system.

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. Limit user privileges on systems to reduce the potential impact of successful exploitation. 3. Monitor for suspicious activities, especially those related to privilege escalation. 4. Implement the principle of least privilege across your environment. 5. Keep all Microsoft systems and software up to date with the latest security updates.

CNNVD | 关于微软多个安全漏洞的通报
近日,微软官方发布了多个安全漏洞的公告,其中微软产品本身漏洞84个,影响到微软产品的其他厂商漏洞5个。
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.
Patch Tuesday August 2024: 6 Zero-Day Vulnerabilities Under Active Exploitation, and Windows Downgrade Attacks
On top of Microsoft releasing fixes for an unusually high number of zero-days and vulnerabilities that are under Active Exploitation, there was also a demonstration of a new Downgrade Attack against Windows that was demonstrated at Black Hat 2024 and Def Con 32 —where an NTLM hash attack was also demonstrated. First demonstrated at Black Hat 2024 and Def Con 32, CVE-2024-21302 Windows Secure Kernel Mode Elevation of Privilege and CVE-2024-38202 are two of the zero-day vulnerabilities that exist in Windows systems that were leveraged by security researcher Alon Leviev with SafeBreach in their proof of concept for a Downgrade Attack with a tool named Windows Downdate.
