How to Fix CVE-2019-14864

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

ansible fixed: 2.7.15 
pip install ansible>=2.7.15
ansible fixed: 2.8.7 
pip install ansible>=2.8.7
ansible fixed: 2.9.1 
pip install ansible>=2.9.1
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 ansible

How to Check if You Are Affected

To determine whether your Python environment is affected by CVE-2019-14864, inspect your installed packages using pip:

pip show ansible

Analyze the terminal output to locate any version of Ansible in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 2.7.15), your application is affected.

Note: The pip show ansible command checks currently installed packages in your active Python environment.

Technical Details

Vulnerability Mechanism & Technical Analysis

This vulnerability is classified under CWE-532: Insertion of Sensitive Information into Log File, where the product writes sensitive information to a log file. In Ansible, 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

Ansible, versions 2.9.x before 2.9.1, 2.8.x before 2.8.7 and Ansible versions 2.7.x before 2.7.15, is not respecting the flag no_log set it to True when Sumologic and Splunk callback plugins are used send tasks results events to collectors. This would discloses and collects any sensitive data.
