{"id":"GHSA-hgc3-hp6x-wpgx","summary":"Antilles Dependency Confusion Vulnerability","details":"### Potential Impact: \nRemote code execution.\n\n### Scope of Impact: \nOpen-source project specific.\n\n### Summary Description:\nA 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). \nMITRE 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.\nThe 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.\n\n### Mitigation Strategy for Customers (what you should do to protect yourself):\nRemove previous versions of Antilles as a precautionary measure and Update to version 1.0.1 or later.\n\n### Acknowledgement:\nThe Antilles team thanks Kotko Vladyslav for reporting this issue.\n\n### References:\nhttps://github.com/lenovo/Antilles/commit/c7b9c5740908b343aceefe69733d9972e64df0b9\n","aliases":["CVE-2021-3840","PYSEC-2021-840"],"modified":"2026-07-08T06:29:27.141445075Z","published":"2021-11-03T17:36:22Z","database_specific":{"cwe_ids":["CWE-427"],"severity":"HIGH","github_reviewed":true,"github_reviewed_at":"2021-11-03T15:04:04Z","nvd_published_at":"2021-11-12T22:15:00Z"},"references":[{"type":"WEB","url":"https://github.com/lenovo/Antilles/security/advisories/GHSA-hgc3-hp6x-wpgx"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2021-3840"},{"type":"WEB","url":"https://github.com/lenovo/Antilles/commit/c7b9c5740908b343aceefe69733d9972e64df0b9"},{"type":"PACKAGE","url":"https://github.com/lenovo/Antilles"},{"type":"WEB","url":"https://github.com/pypa/advisory-database/tree/main/vulns/antilles-tools/PYSEC-2021-840.yaml"}],"affected":[{"package":{"name":"antilles-tools","ecosystem":"PyPI","purl":"pkg:pypi/antilles-tools"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"1.0.1"}]}],"versions":["1.0.0"],"database_specific":{"source":"https://github.com/github/advisory-database/blob/main/advisories/github-reviewed/2021/11/GHSA-hgc3-hp6x-wpgx/GHSA-hgc3-hp6x-wpgx.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:H"},{"type":"CVSS_V4","score":"CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:P/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N"}]}
