Description

Exposure of Sensitive Information to an Unauthorized Actor vulnerability in Apache Airflow. This issue affects Apache Airflow from 2.4.0 to 2.7.0.

Sensitive configuration information has been exposed to authenticated users with the ability to read configuration via Airflow REST API for configuration even when the expose_config option is set to non-sensitive-only. The expose_config option is False by default. It is recommended to upgrade to a version that is not affected if you set expose_config to non-sensitive-only configuration. This is a different error than CVE-2023-45348 which allows authenticated user to retrieve individual configuration values in 2.7.* by specially crafting their request (solved in 2.7.2).

Users are recommended to upgrade to version 2.7.2, which fixes the issue and additionally fixes CVE-2023-45348.

How to fix

Move to the fixed version or later with your package manager, update the lockfile, and run your tests. If the package only arrives through another dependency, upgrade that dependency first. If none of its releases pulls a fixed version yet, force the version with your package manager's override.

Weakness

CWE-200: Exposure of Sensitive Information to an Unauthorized Actor

The product exposes sensitive information to an actor that is not explicitly authorized to have access to that information.

How to prevent it
  • Architecture and Design: Compartmentalize the system to have "safe" areas where trust boundaries can be unambiguously drawn. Do not allow sensitive data to go outside of the trust boundary and always be careful when interfacing with a compartment outside of the safe area. Ensure that appropriate compartmentalization is built into the system design, and the compartmentalization allows for and reinforces privilege separation functionality. Architects and designers should rely on the principle of least privilege to decide the appropriate time to use privileges and the time to drop privileges.
