How to Fix CVE-2022-47951

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

cinder fixed: 19.1.2 
pip install cinder>=19.1.2
cinder fixed: 20.0.2 
pip install cinder>=20.0.2
glance fixed: 23.0.1 
pip install glance>=23.0.1
glance fixed: 24.1.1 
pip install glance>=24.1.1
nova fixed: 24.1.2 
pip install nova>=24.1.2
nova fixed: 25.0.2 
pip install nova>=25.0.2
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 cinder

How to Check if You Are Affected

To determine whether your Python environment is affected by CVE-2022-47951, inspect your installed packages using pip:

pip show cinder

Analyze the terminal output to locate any version of Cinder in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 19.1.2), your application is affected.

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

Technical Details

Vulnerability Mechanism & Technical Analysis

This vulnerability is classified under CWE-22: Improper Limitation of a Pathname to a Restricted Directory ('Path Traversal'), where the product uses external input to construct a pathname that is intended to identify a file or directory that is located underneath a restricted parent directory, but the product does not properly neutralize special elements within the pathname that can cause the pathname to resolve to a location that is outside of the restricted directory. In Cinder, 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

An issue was discovered in OpenStack Cinder before 19.1.2, 20.x before 20.0.2, and 21.0.0; Glance before 23.0.1, 24.x before 24.1.1, and 25.0.0; and Nova before 24.1.2, 25.x before 25.0.2, and 26.0.0. By supplying a specially created VMDK flat image that references a specific backing file path, an authenticated user may convince systems to return a copy of that file's contents from the server, resulting in unauthorized access to potentially sensitive data.
