How to Fix CVE-2024-0937

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

synthcity fixed: Latest secure release 
pip install synthcity>=Latest secure release
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 synthcity

How to Check if You Are Affected

To determine whether your Python environment is affected by CVE-2024-0937, inspect your installed packages using pip:

pip show synthcity

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

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

Technical Details

Vulnerability Mechanism & Technical Analysis

This vulnerability is classified under CWE-502: Deserialization of Untrusted Data, where the product deserializes untrusted data without sufficiently ensuring that the resulting data will be valid. In Synthcity, 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

A vulnerability, which was classified as critical, has been found in van_der_Schaar LAB synthcity 0.2.9. Affected by this issue is the function load_from_file of the component PKL File Handler. The manipulation leads to deserialization. The attack may be launched remotely. The exploit has been disclosed to the public and may be used. VDB-252182 is the identifier assigned to this vulnerability. NOTE: The vendor was contacted early and confirmed immediately the existence of the issue. A patch is planned to be released in February 2024.
