{"id":"PYSEC-2024-244","details":"A path traversal vulnerability exists in mlflow/mlflow version 2.11.0, identified as a bypass for the previously addressed CVE-2023-6909. The vulnerability arises from the application's handling of artifact URLs, where a '#' character can be used to insert a path into the fragment, effectively skipping validation. This allows an attacker to construct a URL that, when processed, ignores the protocol scheme and uses the provided path for filesystem access. As a result, an attacker can read arbitrary files, including sensitive information such as SSH and cloud keys, by exploiting the way the application converts the URL into a filesystem path. The issue stems from insufficient validation of the fragment portion of the URL, leading to arbitrary file read through path traversal.","aliases":["BIT-mlflow-2024-3848","CVE-2024-3848","GHSA-rfqq-wq6w-72jm"],"modified":"2025-04-08T10:58:22.843207Z","published":"2024-05-16T09:15:14Z","references":[{"type":"WEB","url":"https://huntr.com/bounties/8d5aadaa-522f-4839-b41b-d7da362dd610"},{"type":"FIX","url":"https://github.com/mlflow/mlflow/commit/f8d51e21523238280ebcfdb378612afd7844eca8"}],"affected":[{"package":{"name":"mlflow","ecosystem":"PyPI","purl":"pkg:pypi/mlflow"},"ranges":[{"type":"GIT","repo":"https://github.com/mlflow/mlflow","events":[{"introduced":"0"},{"fixed":"f8d51e21523238280ebcfdb378612afd7844eca8"},{"fixed":"f8d51e21523238280ebcfdb378612afd7844eca8"}]},{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"2.12.1"}]}],"versions":["0.0.1","0.1.0","0.2.0","0.2.1","0.3.0","0.4.0","0.4.1","0.4.2","0.5.0","0.5.1","0.5.2","0.6.0","0.7.0","0.8.0","0.8.1","0.8.2","0.9.0","0.9.0.1","0.9.1","1.0.0","1.1.0","1.1.1.dev0","1.10.0","1.11.0","1.12.0","1.12.1","1.13","1.13.1","1.14.0","1.14.1","1.15.0","1.16.0","1.17.0","1.18.0","1.19.0","1.2.0","1.20.0","1.20.1","1.20.2","1.21.0","1.22.0","1.23.0","1.23.1","1.24.0","1.25.0","1.25.1","1.26.0","1.26.1","1.27.0","1.28.0","1.29.0","1.3.0","1.30.0","1.30.1","1.4.0","1.5.0","1.6.0","1.7.0","1.7.1","1.7.2","1.8.0","1.9.0","1.9.1","2.0.0","2.0.0rc0","2.0.1","2.1.0","2.1.1","2.10.0","2.10.1","2.10.2","2.11.0","2.11.1","2.11.2","2.11.3","2.11.4","2.12.0","2.2.0","2.2.1","2.2.2","2.3.0","2.3.1","2.3.2","2.4.0","2.4.1","2.4.2","2.5.0","2.6.0","2.7.0","2.7.1","2.8.0","2.8.1","2.9.0","2.9.1","2.9.2"],"database_specific":{"source":"https://github.com/pypa/advisory-database/blob/main/vulns/mlflow/PYSEC-2024-244.yaml"}}],"schema_version":"1.7.3","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:N"}]}
