How to Fix CVE-2013-2030

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

python-keystoneclient fixed: 0.2.4 
pip install python-keystoneclient>=0.2.4
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 python-keystoneclient

How to Check if You Are Affected

To determine whether your Python environment is affected by CVE-2013-2030, inspect your installed packages using pip:

pip show python-keystoneclient

Analyze the terminal output to locate any version of Python keystoneclient in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 0.2.4), your application is affected.

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

Technical Details

Vulnerability Mechanism & Technical Analysis

This vulnerability is classified under CWE-1188: Initialization of a Resource with an Insecure Default, where the product initializes or sets a resource with a default that is intended to be changed by the product's installer, administrator, or maintainer, but the default is not secure. In Python keystoneclient, 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

keystone/middleware/auth_token.py in OpenStack Nova Folsom, Grizzly, and Havana uses an insecure temporary directory for storing signing certificates, which allows local users to spoof servers by pre-creating this directory, which is reused by Nova, as demonstrated using /tmp/keystone-signing-nova on Fedora.
