How to Fix CVE-2015-9543

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

Nova fixed: 18.2.4

pip install Nova>=18.2.4

Nova fixed: 19.1.0

pip install Nova>=19.1.0

Nova fixed: 20.1.0

pip install Nova>=20.1.0

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 Nova

How to Check if You Are Affected

To determine whether your Python environment is affected by CVE-2015-9543, inspect your installed packages using pip:

pip show Nova

Analyze the terminal output to locate any version of Nova in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 18.2.4), your application is affected.

Note: The pip show Nova 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 Nova, 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 Nova before 18.2.4, 19.x before 19.1.0, and 20.x before 20.1.0. It can leak consoleauth tokens into log files. An attacker with read access to the service's logs may obtain tokens used for console access. All Nova setups using novncproxy are affected. This is related to `NovaProxyRequestHandlerBase.new_websocket_client` in `console/websocketproxy.py`.
