How to Fix CVE-2015-5271

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

tripleo-heat-templates fixed: 0.8.7 
pip install tripleo-heat-templates>=0.8.7
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 tripleo-heat-templates

How to Check if You Are Affected

To determine whether your Python environment is affected by CVE-2015-5271, inspect your installed packages using pip:

pip show tripleo-heat-templates

Analyze the terminal output to locate any version of Tripleo heat templates in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 0.8.7), your application is affected.

Note: The pip show tripleo-heat-templates 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 Tripleo heat templates, 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 TripleO Heat templates (tripleo-heat-templates) do not properly order the Identity Service (keystone) before the OpenStack Object Storage (Swift) staticweb middleware in the swiftproxy pipeline when the staticweb middleware is enabled, which might allow remote attackers to obtain sensitive information from private containers via unspecified vectors.
