CVE-2023-22884: Apache Airflow Command Injection Vulnerability

Background

Apache Airflow is an open-source platform used for programmatically authoring, scheduling, and monitoring workflows. It provides a rich set of tools and features for managing complex data pipelines. The Apache Airflow MySQL Provider is a plugin that allows Airflow to interact with MySQL databases. This vulnerability affects versions of Apache Airflow prior to 2.5.1 and Apache Airflow MySQL Provider prior to 4.0.0.

Vulnerability Detail

The vulnerability identified as CVE-2023-22884 is an instance of Command Injection. It occurs due to improper neutralization of special elements used in a command. An attacker can exploit this vulnerability by injecting malicious commands into certain input fields, leading to arbitrary command execution. This can result in various consequences, including unauthorized access, data manipulation, and system compromise. The severity of this vulnerability is rated as Critical with a CVSS v3 score of 9.8 (CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H).

Workaround

As a temporary workaround, it is advised to sanitize and validate user input before using it in command execution. This can be achieved by implementing input validation and using parameterized queries or prepared statements to prevent command injection attacks. Here is an example of input validation in Python using the subprocess module:

import subprocess

user_input = input('Enter a command: ')

# Validate and sanitize user input
if not user_input.isalnum():
    print('Invalid input')
    exit()

# Execute the command
subprocess.run(['ls', user_input])

Conclusion

In conclusion, the CVE-2023-22884 vulnerability in Apache Airflow and Apache Airflow MySQL Provider allows for command injection, potentially leading to unauthorized access and system compromise. It is crucial to upgrade to the latest versions of these packages and implement proper input validation to mitigate this vulnerability.
