Summary

CVE-2023-40195 involves deserialization of untrusted data in the Apache Airflow Spark Provider, allowing authorized users to execute arbitrary code on the Airflow node by pointing to a malicious Spark server.

Risk Assessment

Organizations may face serious security risks if unauthorized users gain access to Spark hook configuration capabilities, potentially leading to the execution of malicious code.

Recommendation

Administrators are advised to review their configurations carefully and grant Spark hook configuration permissions only to fully trusted users.

Other vulnerabilities in Apache Airflow Spark Provider

CVE-2023-40272High
Apache Airflow Spark Provider, versions before 4.1.3, is affected by a vulnerability that allows an attacker to pass in malicious parameters when establishing a connection, giving an opportunity to read files on the Airflow server.

Original NVD description (English source)

Deserialization of Untrusted Data, Inclusion of Functionality from Untrusted Control Sphere vulnerability in Apache Software Foundation Apache Airflow Spark Provider. When the Apache Spark provider is installed on an Airflow deployment, an Airflow user that is authorized to configure Spark hooks can effectively run arbitrary code on the Airflow node by pointing it at a malicious Spark server. Prior to version 4.1.3, this was not called out in the documentation explicitly, so it is possible that administrators provided authorizations to configure Spark hooks without taking this into account. We recommend administrators to review their configurations to make sure the authorization to configure Spark hooks is only provided to fully trusted users.
