Risks in Airflow Version 2.5.2 – Unauthenticated Page Vulnerability

Problem:

The user was unable to reach the application page and received the error ‘Unauthenticated Page’.

Process:

Step 1: Initial Investigation

The security issue pertains to an unauthenticated page within the Airflow version 2.5.2 instance. This unauthenticated page poses a potential security risk, as it can be accessed without proper authentication, potentially exposing sensitive information or functionality.

Step 2: Test on the v. 2.7.0

The issue didn’t reproduce on version 2.7.0

Solution:

To enhance the security of the Airflow instance, two key measures are recommended:

1. Implementing an HTTPS Certificate: It is strongly advised to implement an HTTPS certificate for the Airflow instance. This measure ensures that all communication between users and the Airflow server is encrypted, mitigating the risk of unauthorized access and data interception. This step is crucial in safeguarding sensitive information.

2. Restricting Access via VPN: Another effective security measure is to limit access to Airflow solely through a Virtual Private Network (VPN). By setting up a VPN and providing dedicated user profiles, access to Airflow and other applications can be controlled. Employees will only be able to access Airflow if they have VPN access. Assistance can be provided in configuring the VPN and setting up security groups for the Airflow instances.

Conclusion:

After investigation and other troubleshooting measures provided to the user, the issue was resolved. The security issue discovered in Airflow version 2.5.2 involves an unauthenticated page, potentially exposing sensitive information or functionality due to its accessibility without proper authentication. Upon testing version 2.7.0, the issue was not replicated. To address this vulnerability and enhance Airflow’s security, implementing an HTTPS certificate and restricting access via a Virtual Private Network (VPN) are recommended measures. These steps aim to encrypt communication, prevent unauthorized access, and ensure controlled access to Airflow and associated applications.
