CVE-2024-38189 - Uncovering the Microsoft Project Remote Code Execution Vulnerability: Explanation, Exploits, and Solutions

Remote Code Execution (RCE) vulnerabilities are always a high priority for developers and security teams. In this long-read post, we'll dive deep into the details of CVE-2024-38189 - a critical RCE vulnerability found in Microsoft Project. We'll discuss the problem's root cause, provide code snippets that demonstrate the issue, and link to original sources and references. Finally, we'll explore potential exploits and effective solutions to help you address this vulnerability.

The Root Cause of CVE-2024-38189

CVE-2024-38189 affects Microsoft Project, a popular project management software package. According to the official CVE record (https://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2024-38189), this vulnerability is caused by improper handling of certain file types, which can lead to remote code execution if a user views or interacts with a specially crafted Project file.

The following code snippet demonstrates a simple representation of the vulnerability

# This is an example code snippet. Do not use this code in production.
import os
import subprocess

def process_project_file(file_path):
    # Read the contents of the project file
    with open(file_path, 'r') as file:
        content = file.read()

    # Perform the vulnerable operation
    subprocess.call(content, shell=True)

# Example usage: process_project_file('malicious_project_file.mpp')

In the code above, the process_project_file function reads the content of a project file and uses the subprocess.call() function to execute the content as a shell command. This is an example of how an application might improperly handle project files, potentially allowing remote code execution.
