Antilles Dependency Confusion Vulnerability
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.
