- 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.…
Recommended action: Upgrade to 1.0.1 or later, then redeploy and verify.A vendor fix does not resolve your finding until you verify it in your own systems.
