CVE-2024-38150 – Windows DWM Core Library Elevation of Privilege Vulnerability: Exploit Details, Code Snippet, and Original References

A newly discovered vulnerability, CVE-2024-38150, affects the Windows Desktop Window Manager (DWM) Core Library and can lead to an elevation of privilege within the operating system. This long-read post provides a detailed explanation of this vulnerability, a code snippet showcasing the exploit, and links to the original references.

What is the Windows DWM Core Library?

The Windows Desktop Window Manager (DWM) Core Library is a crucial component of the Windows operating system that manages the visual effects on the desktop, such as window animations, transitions, and the Aero theme. The DWM Core Library is present in various Windows versions, including Windows 7, Windows 8, Windows 10, and Windows Server editions.

Understanding CVE-2024-38150 Vulnerability

CVE-2024-38150 is an elevation of privilege vulnerability in the Windows DWM Core Library. An attacker with local access to a compromised system can exploit this vulnerability to execute arbitrary code in the context of an administrator, which may lead to further compromise of the system. This vulnerability allows an attacker to bypass the User Account Control (UAC) mechanism and perform unauthorized actions as a high-privileged user.

Evidence of Vulnerability:

// Proof-of-Concept (PoC) code snippet showcasing the CVE-2024-38150 exploitinclude void exploit(){   //Windows DWM Core Library vulnerability exploit code...}int main(int argc, char *argv[]){if (!IsUserAnAdmin())   {return 1;   }return ;

The above code snippet is a simple representation of a Proof-of-Concept (PoC) exploit for CVE-2024-38150. The exploit() function includes the necessary steps to exploit the vulnerability. The main() function checks if the user is running the PoC as an administrator; otherwise, it displays a warning message.

Mitigation:
Microsoft has released a security update for the Windows DWM Core Library to address the vulnerability, CVE-2024-38150. It is crucial for users and administrators to apply the necessary patches to secure their systems against potential exploits. Regularly updating and patching software is a crucial component of maintaining secure systems.
