How to Fix CVE-2024-29189

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

ansys-geometry-core fixed: 0.3.3 
pip install ansys-geometry-core>=0.3.3
ansys-geometry-core fixed: 0.4.12 
pip install ansys-geometry-core>=0.4.12
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 ansys-geometry-core

How to Check if You Are Affected

To determine whether your Python environment is affected by CVE-2024-29189, inspect your installed packages using pip:

pip show ansys-geometry-core

Analyze the terminal output to locate any version of Ansys geometry core in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 0.3.3), your application is affected.

Note: The pip show ansys-geometry-core command checks currently installed packages in your active Python environment.

Technical Details

Vulnerability Mechanism & Technical Analysis

This vulnerability is classified under CWE-78: Improper Neutralization of Special Elements used in an OS Command ('OS Command Injection'), where the product constructs all or part of an os command using externally-influenced input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could modify the intended os command when it is sent to a downstream component. In Ansys geometry core, 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.
