CVE-2024-38076 - Windows Remote Desktop Licensing Service Remote Code Execution Vulnerability: Exploit Details, Code Snippets, and References

As cybersecurity researchers continue to discover and report new vulnerabilities, it is essential for users and administrators to keep pace with the latest news and patches. In this post, we will dive deep into the details of CVE-2024-38076, a vulnerability that affects Windows Remote Desktop Licensing Service and can lead to remote code execution. With code snippets, original references, and exploit details, this post aims to shed light on the vulnerability and provide practical solutions for mitigation.

CVE-2024-38076: Vulnerability Summary

The CVE-2024-38076 vulnerability allows an attacker to remotely execute arbitrary code on a targeted system via the Windows Remote Desktop Licensing Service (RD Licensing), which is a part of the Microsoft Remote Desktop Services (RDS) suite. This vulnerability has been given a CVSS (Common Vulnerability Scoring System) score of 9.8 out of 10, which indicates a critical impact level. Successful exploitation of this vulnerability could enable attackers to gain full control over a compromised system, potentially affecting the confidentiality, integrity, and availability of sensitive information and resources.

Exploiting CVE-2024-38076

To successfully exploit this vulnerability, an attacker must craft specially formulated license request packets and send them to a Remote Desktop Licensing Service instance running on a targeted system. By doing so, the attacker can trigger a buffer overflow condition within the service, leading to the execution of arbitrary code with system-level privileges.

The following code snippet demonstrates an example of exploiting the vulnerability

import socket

def send_payload(target_ip, target_port, payload):
    s = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
    s.connect((target_ip, target_port))
    
    s.sendall(payload)
    response = s.recv(1024)
    s.close()

    return response

def craft_exploit_payload():
    # The malicious payload that triggers the buffer overflow
    # and executes arbitrary code on the target system.
    
    # [Redacted for security reasons]
    pass

def main():
    target_ip = "192.168.1.10"
    target_port = 12345
    payload = craft_exploit_payload()

    response = send_payload(target_ip, target_port, payload)
    print("Exploit sent. Response: " + response)

if __name__ == "__main__":
    main()

Mitigation and Patching

The best way to protect your systems from this vulnerability is to apply the necessary patches provided by Microsoft. Links to the security updates and guidance for each affected component can be found in the original reference links:
