pip install ceph-deploy>=1.5.25
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 ceph-deploy

How to Check if You Are Affected

To determine whether your Python environment is affected by CVE-2015-4053, inspect your installed packages using pip:

pip show ceph-deploy

Analyze the terminal output to locate any version of Ceph deploy in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 1.5.25), your application is affected.

Note: The pip show ceph-deploy 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 Ceph deploy, 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 admin command in ceph-deploy before 1.5.25 uses world-readable permissions for `/etc/ceph/ceph.client.admin.keyring`, which allows local users to obtain sensitive information by reading the file.
