How to Fix CVE-2019-3895

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

octavia fixed: 0.9.0 
pip install octavia>=0.9.0
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 octavia

How to Check if You Are Affected

To determine whether your Python environment is affected by CVE-2019-3895, inspect your installed packages using pip:

pip show octavia

Analyze the terminal output to locate any version of Octavia in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 0.9.0), your application is affected.

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

Technical Details

Vulnerability Mechanism & Technical Analysis

This vulnerability is classified under CWE-284: Improper Access Control, where the product does not restrict or incorrectly restricts access to a resource from an unauthorized actor. In Octavia, 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

### Description An access-control flaw was found in the Octavia service when the cloud platform was deployed using Red Hat OpenStack Platform Director. An attacker could cause new amphorae to run based on any arbitrary image. This meant that a remote attacker could upload a new amphorae image and, if requested to spawn new amphorae, Octavia would then pick up the compromised image. ### Mitigation To prevent this vulnerability: 1. Update Octavia's configuration setting (octavia.conf) to `amp_image_owner_id = $UUID_OF_SERVICE_PROJECT` on all Octavia nodes. 2. Enable the new configuration by restarting both `octavia_worker` and `octavia_health_manager`.
