How to Fix CVE-2021-3840

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

antilles-tools fixed: 1.0.1 
pip install antilles-tools>=1.0.1
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 antilles-tools

How to Check if You Are Affected

To determine whether your Python environment is affected by CVE-2021-3840, inspect your installed packages using pip:

pip show antilles-tools

Analyze the terminal output to locate any version of Antilles tools in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 1.0.1), your application is affected.

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

Technical Details

Vulnerability Mechanism & Technical Analysis

This vulnerability is classified under CWE-427: Uncontrolled Search Path Element, where the product uses a fixed or controlled search path to find resources, but one or more locations in that path can be under the control of unintended actors. In Antilles tools, 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

### Potential Impact: Remote code execution. ### Scope of Impact: Open-source project specific. ### Summary Description: A dependency confusion vulnerability was reported in the Antilles open-source software prior to version 1.0.1 that could allow for remote code execution during installation due to a package listed in requirements.txt not existing in the public package index (PyPi). MITRE classifies this weakness as an Uncontrolled Search Path Element (CWE-427) in which a private package dependency may be replaced by an unauthorized package of the same name published to a well-known public repository such as PyPi. The configuration has been updated to only install components built by Antilles, removing all other public package indexes. Additionally, the antilles-tools dependency has been published to PyPi. ### Mitigation Strategy for Customers (what you should do to protect yourself): Remove previous versions of Antilles as a precautionary measure and Update to version 1.0.1 or later. ### Acknowledgement: The Antilles team thanks Kotko Vladyslav for reporting this issue. ### References: https://github.com/lenovo/Antilles/commit/c7b9c5740908b343aceefe69733d9972e64df0b9
