How to Fix CVE-2016-4985

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

ironic fixed: 4.2.5 
pip install ironic>=4.2.5
ironic fixed: 5.1.2 
pip install ironic>=5.1.2
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 ironic

How to Check if You Are Affected

To determine whether your Python environment is affected by CVE-2016-4985, inspect your installed packages using pip:

pip show ironic

Analyze the terminal output to locate any version of Ironic in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 4.2.5), your application is affected.

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

Technical Details

Vulnerability Mechanism & Technical Analysis

This vulnerability is classified under CWE-200: Exposure of Sensitive Information to an Unauthorized Actor, where the product exposes sensitive information to an actor that is not explicitly authorized to have access to that information. In Ironic, 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

The ironic-api service in OpenStack Ironic before 4.2.5 (Liberty) and 5.x before 5.1.2 (Mitaka) allows remote attackers to obtain sensitive information about a registered node by leveraging knowledge of the MAC address of a network card belonging to that node and sending a crafted POST request to the `v1/drivers/$DRIVER_NAME/vendor_passthru` resource.
