How to Fix CVE-2016-4972

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

murano fixed: 1.0.3 
pip install murano>=1.0.3
murano-dashboard fixed: 1.0.3 
pip install murano-dashboard>=1.0.3
murano-dashboard fixed: 2.0.1 
pip install murano-dashboard>=2.0.1
python-muranoclient fixed: 0.7.3 
pip install python-muranoclient>=0.7.3
python-muranoclient fixed: 0.8.5 
pip install python-muranoclient>=0.8.5
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 murano

How to Check if You Are Affected

To determine whether your Python environment is affected by CVE-2016-4972, inspect your installed packages using pip:

pip show murano

Analyze the terminal output to locate any version of Murano in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 1.0.3), your application is affected.

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

Technical Details

Vulnerability Mechanism & Technical Analysis

This vulnerability is classified under CWE-20: Improper Input Validation, where the product receives input or data, but it does not validate or incorrectly validates that the input has the properties that are required to process the data safely and correctly. In Murano, 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

OpenStack Murano before 1.0.3 (liberty) and 2.x before 2.0.1 (mitaka), Murano-dashboard before 1.0.3 (liberty) and 2.x before 2.0.1 (mitaka), and python-muranoclient before 0.7.3 (liberty) and 0.8.x before 0.8.5 (mitaka) improperly use loaders inherited from yaml.Loader when parsing MuranoPL and UI files, which allows remote attackers to create arbitrary Python objects and execute arbitrary code via crafted extended YAML tags in UI definitions in packages.
