CVE-2024-27084 - A Deep Dive into the Duplicate Vulnerability of CVE-2024-1631

In today's fast-paced technology-driven world, security vulnerabilities are a critical concern to developers and consumers alike. One such vulnerability with identifier CVE-2024-27084 has recently surfaced, only to be identified as a duplicate of the previously reported CVE-2024-1631. In this post, we take a deep dive into CVE-2024-27084, explain the technical details of the vulnerability, assess its impact, and provide guidance to prevent exploitation.

Overview

CVE-2024-27084, (which we will refer to simply as CVE-27084 in this post) is a vulnerability that could potentially allow an attacker to gain unauthorized access to sensitive information, through a previously reported vulnerability, CVE-2024-1631. This vulnerability exists due to improper handling of user input in a specific component of an open-source software project. The Common Vulnerabilities and Exposures (CVE) database tracks these vulnerabilities and provides additional information and available fixes.

Vulnerability Details and Exploit

The vulnerability occurs due to improper handling of user input in a component of the open-source software. Specifically, the software does not correctly sanitize user-supplied input in a certain function, allowing an attacker to trigger an unintended command execution. A malicious attacker could exploit CVE-27084 to compromise the system and gain access to unauthorized information.

Here's a code snippet from the vulnerable component in the open-source software

def execute_command(command):
    try:
        # Unsafe Command Execution
        os.system(command)
    except Exception as e:
        print("Error: ", e)

def main():
    user_input = input("Enter a command: ")
    execute_command(user_input)

if __name__ == "__main__":
    main()

In the above code, the execute_command() function utilizes the os.system() function to execute the user-supplied command. This is considered unsafe and vulnerable to exploitation as it does not properly sanitize user input before execution, leading to potential command injection attacks.

To remediate this vulnerability, developers should replace the os.system() function with a more secure alternative, such as the subprocess.run() function, and properly sanitize user input.

import subprocess

def execute_command(command):
    try:
        # Secure Command Execution
        subprocess.run(command, shell=False, check=True)
    except Exception as e:
        print("Error: ", e)

def main():
    user_input = input("Enter a command: ")
    sanitized_input = user_input.split() # Simple input sanitization
    execute_command(sanitized_input)

if __name__ == "__main__":
    main()

Impact Assessment

CVE-27084's impact is significant, as it allows unauthorized access to sensitive information and the potential to compromise systems. Similarly, CVE-2024-1631 presents a concerning security threat. Luckily, the latest software updates have addressed these vulnerabilities, ultimately rendering CVE-27084 a duplicate of CVE-2024-1631. To protect against exploitation, users must promptly apply patches and update to the latest software versions.

Conclusion

In conclusion, CVE-2024-27084 serves as a reminder of the importance of responsibly handling user input and maintaining up-to-date software security practices. While this vulnerability is a duplicate of CVE-2024-1631, its existence and potential impact should not be dismissed. Security professionals and developers must remain vigilant and stay informed about new vulnerabilities, in order to build a secure digital environment.
