How to Fix CVE-2019-10206

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: 2.8.4 
pip install ansible>=2.8.4
ansible fixed: 2.7.13 
pip install ansible>=2.7.13
ansible fixed: 2.6.19 
pip install ansible>=2.6.19
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-2019-10206, 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 2.8.4), 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-522: Insufficiently Protected Credentials, where the product transmits or stores authentication credentials, but it uses an insecure method that is susceptible to unauthorized interception and/or retrieval. 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-playbook -k and ansible cli tools, all versions 2.8.x before 2.8.4, all 2.7.x before 2.7.13 and all 2.6.x before 2.6.19, prompt passwords by expanding them from templates as they could contain special characters. Passwords should be wrapped to prevent templates trigger and exposing them.
