How to Fix CVE-2024-34715

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: 2.37.0 
pip install ethyca-fides>=2.37.0
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 ethyca-fides

How to Check if You Are Affected

To determine whether your Python environment is affected by CVE-2024-34715, 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 2.37.0), 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-116: Improper Encoding or Escaping of Output, where the product prepares a structured message for communication with another component, but encoding or escaping of the data is either missing or done incorrectly. as a result, the intended structure of the message is not preserved. 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

The Fides webserver requires a connection to a hosted PostgreSQL database for persistent storage of application data. If the password used by the webserver for this database connection includes special characters such as `@` and `$`, webserver startup fails and the part of the password following the special character is exposed in webserver error logs. This is caused by improper escaping of the SQLAlchemy password string, see [here](https://docs.sqlalchemy.org/en/14/core/engines.html#escaping-special-characters-such-as-signs-in-passwords) and [here](https://github.com/sqlalchemy/sqlalchemy/discussions/6615) for more info. ### Impact Partial exposure of hosted database password in webserver logs ### Patches The vulnerability has been patched in Fides version `2.37.0`. Users are advised to upgrade to this version or later to secure their systems against this threat. ### Workarounds There are no workarounds. ### Proof of Concept 1. Create a hosted PostgreSQL database for Fides with a password including `@` or `$` e.g. `p@ssword` 2. Run Fides and observe failure, sample log attached ``` fides | 2024-02-28 14:27:52.609 | ERROR | fides.api.db.database:configure_db:117 - Unable to configure database: sqlalchemy.exc.OperationalError: (psycopg2.OperationalError) could not translate host name "ssword@fides-db" to address: Name or service not known ```
