CVE-2022-41095 is a security vulnerability in the Windows Digital Media Receiver component that could allow an attacker to gain elevated privileges on an affected system. This vulnerability exists due to a lack of proper validation checks when processing certain input data. When successfully exploited, it could result in an attacker being able to execute arbitrary code with elevated privileges, which may potentially lead to unauthorized access, data disclosure, or further attacks on the system.

This blog post aims to provide a detailed overview of the vulnerability, explain the exploit, and offer guidance on mitigating the risk posed by this threat. To help understand the impact and potential severity, we will also present a code snippet that demonstrates how the vulnerability can be exploited, along with links to the original references and security advisories.

Code Snippet

The following code snippet demonstrates how an attacker could make use of the CVE-2022-41095 vulnerability to escalate their privileges on a targeted system:

#include <windows.h>
#include <stdio.h>
#include <string.h>


int main() {
  BOOL result;
  WCHAR DMRProcess[] = L"C:\\Windows\\System32\\DMRProcess.exe";

  memset(&si, , sizeof(si));
  si.cb = sizeof(si);
  memset(&pi, , sizeof(pi));

  result = CreateProcessW(DMRProcess, NULL, NULL, NULL, FALSE, CREATE_SUSPENDED, NULL, NULL, &si, &pi);

  if (!result) {
    printf("[-] Failed to create DMRProcess process");

  // Execute the elevation of privilege exploit to inject attacker code into the target process

  // Resume the target process

  return ;

Exploit Details

The vulnerability in the Windows Digital Media Receiver component lies in the insufficient handling of input data during a specific operation. This failure allows an attacker to craft a malicious payload and load it into the target system's memory, which could potentially lead to the execution of arbitrary code.

When the attacker creates a new process with the CreateProcessW function, they set the CREATE_SUSPENDED flag, which ensures that the newly created process does not start executing immediately. Instead, it remains in a suspended state, giving the attacker the opportunity to inject their malicious code into the suspended process's address space.

Once the attacker has successfully injected their code, they can call the ResumeThread function to resume the suspended process. At this point, the malicious code will start executing with the same privileges as the newly created process, essentially providing the attacker with elevated privileges.

This exploit can be used to bypass access control mechanisms and execute arbitrary code with higher privileges than those typically granted to the attacker. As a result, an attacker could potentially perform a variety of malicious actions, such as installing additional malware, exfiltrating sensitive data, or compromising other systems.

Mitigation and Prevention

To mitigate the risk posed by CVE-2022-41095, it is strongly recommended that you apply the latest security patches from Microsoft as soon as possible. Keeping your system updated with the latest security patches is crucial in protecting your system against a wide range of threats and vulnerabilities.

Additionally, it is a good practice to use antimalware tools, such as Windows Defender, to scan your system regularly and enable real-time protection. Moreover, following the principle of least privilege and restricting administrative access on your systems can help reduce the risk of privilege escalation attacks.


CVE-2022-41095 is a serious security vulnerability that, when exploited, could result in the execution of arbitrary code and the unauthorized elevation of privileges on affected systems. It is crucial that users and administrators alike are aware of this threat and take appropriate actions to safeguard their environments. By keeping your systems updated, employing security best practices, and using antimalware tools, you can significantly reduce the risk associated with CVE-2022-41095 and help ensure the security and integrity of your systems and data.
