How to Fix CVE-2023-46124

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

ethyca-fides fixed: 2.22.1 
pip install ethyca-fides>=2.22.1
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 ethyca-fides

How to Check if You Are Affected

To determine whether your Python environment is affected by CVE-2023-46124, inspect your installed packages using pip:

pip show ethyca-fides

Analyze the terminal output to locate any version of Ethyca fides in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 2.22.1), your application is affected.

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

Technical Details

Vulnerability Mechanism & Technical Analysis

This vulnerability is classified under CWE-918: Server-Side Request Forgery (SSRF), where the web server receives a url or similar request from an upstream component and retrieves the contents of this url, but it does not sufficiently ensure that the request is being sent to the expected destination. In Ethyca fides, 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

### Impact The Fides web application allows a custom integration to be uploaded as a ZIP file containing configuration and dataset definitions in YAML format. It was discovered that specially crafted YAML dataset and config files allow a malicious user to perform arbitrary requests to internal systems and exfiltrate data outside the environment (also known as a Server-Side Request Forgery). The application does not perform proper validation to block attempts to connect to internal (including localhost) resources. Exploitation is limited to API clients with the `CONNECTOR_TEMPLATE_REGISTER` authorization scope. In the Fides Admin UI this scope is restricted to highly privileged users, specifically root users and users with the owner role. ### Patches The vulnerability has been patched in Fides version `2.22.1`. Users are advised to upgrade to this version or later to secure their systems against this threat. ### Workarounds There are no workarounds.
