How to Fix CVE-2023-39441

To remediate this vulnerability, upgrade all affected Apache airflow providers smtp dependencies to a patched release. Both direct and transitive dependencies should be checked, as frameworks or security libraries may pull in vulnerable versions transitively.

apache-airflow-providers-smtp fixed: 1.3.0 
pip install apache-airflow-providers-smtp>=1.3.0
apache-airflow-providers-imap fixed: 3.3.0 
pip install apache-airflow-providers-imap>=3.3.0
apache-airflow fixed: 2.7.0 
pip install apache-airflow>=2.7.0
Verify Direct and Transitive Dependencies

Run the following command in your project directory to verify that all resolved dependencies use the patched release: 

pip show apache-airflow-providers-smtp

How to Check if You Are Affected

To determine whether your Python environment is affected by CVE-2023-39441, inspect your installed packages using pip:

pip show apache-airflow-providers-smtp

Analyze the terminal output to locate any version of Apache airflow providers smtp in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 1.3.0), your application is affected.

Note: The pip show apache-airflow-providers-smtp command checks currently installed packages in your active Python environment.

Technical Details

Vulnerability Mechanism & Technical Analysis

This vulnerability is classified under CWE-295: Improper Certificate Validation, where the product does not validate, or incorrectly validates, a certificate. In Apache airflow providers smtp, software state validation or input boundaries are circumvented during processing. Review the official source advisory statement below for specific affected components, classes, and reproduction details.

Source Advisory Statement

Apache Airflow SMTP Provider before 1.3.0, Apache Airflow IMAP Provider before 3.3.0, and Apache Airflow before 2.7.0 are affected by the Validation of OpenSSL Certificate vulnerability. The default SSL context with SSL library did not check a server's X.509 certificate.  Instead, the code accepted any certificate, which could result in the disclosure of mail server credentials or mail contents when the client connects to an attacker in a MITM position. Users are strongly advised to upgrade to Apache Airflow version 2.7.0 or newer, Apache Airflow IMAP Provider version 3.3.0 or newer, and Apache Airflow SMTP Provider version 1.3.0 or newer to mitigate the risk associated with this vulnerability
