{"cve":"CVE-2024-0520","nvd":{"published":"2024-06-06T19:15:51.187","modified":"2026-06-17T06:53:41.303","status":"Modified","description":"A vulnerability in mlflow/mlflow version 8.2.1 allows for remote code execution due to improper neutralization of special elements used in an OS command ('Command Injection') within the `mlflow.data.http_dataset_source.py` module. Specifically, when loading a dataset from a source URL with an HTTP scheme, the filename extracted from the `Content-Disposition` header or the URL path is used to generate the final file path without proper sanitization. This flaw enables an attacker to control the file path fully by utilizing path traversal or absolute path techniques, such as '../../tmp/poc.txt' or '/tmp/poc.txt', leading to arbitrary file write. Exploiting this vulnerability could allow a malicious user to execute commands on the vulnerable machine, potentially gaining access to data and model information. The issue is fixed in version 2.9.0.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:H","score":8.8},"cwes":["CWE-22"],"references":["https://github.com/mlflow/mlflow/commit/400c226953b4568f4361bc0a0c223511652c2b9d","https://huntr.com/bounties/93e470d7-b6f0-409b-af63-49d3e2a26dbc","https://github.com/mlflow/mlflow/commit/400c226953b4568f4361bc0a0c223511652c2b9d","https://huntr.com/bounties/93e470d7-b6f0-409b-af63-49d3e2a26dbc"],"products":["lfprojects:mlflow"],"source":"nvd","synced_at":"2026-10-19T21:51:20.603330631+00:00"},"epss":{"cve":"CVE-2024-0520","score":0.02401,"percentile":0.84041,"date":"2026-10-31"},"kev":null,"osv":[{"id":"GHSA-5q6c-ffvg-xcm9","url":"https://osv.dev/vulnerability/GHSA-5q6c-ffvg-xcm9","summary":"Remote code execution in mlflow","modified":"2025-04-08T22:30:40.119861Z","packages":[{"ecosystem":"PyPI","name":"mlflow","purl":"pkg:pypi/mlflow","ranges":["<2.9.0"],"fixed":["2.9.0"]}]},{"id":"PYSEC-2024-239","url":"https://osv.dev/vulnerability/PYSEC-2024-239","summary":"","modified":"2026-06-10T17:01:26.015570628Z","packages":[{"ecosystem":"PyPI","name":"mlflow","purl":"pkg:pypi/mlflow","ranges":["<2.9.0"],"fixed":["2.9.0"]}]}],"attribution":["This product uses the NVD API but is not endorsed or certified by the NVD.","EPSS scores: FIRST Exploit Prediction Scoring System, https://www.first.org/epss","Known exploited vulnerabilities: CISA Known Exploited Vulnerabilities Catalog, https://www.cisa.gov/known-exploited-vulnerabilities-catalog","Package advisories: OSV (https://osv.dev), from the GitHub Advisory Database, PyPA, Go, RustSec and other ecosystem databases, under CC-BY 4.0 or CC0","CVE records: the CVE Program's CVE List (https://www.cve.org), under its terms of use (https://www.cve.org/Legal/TermsOfUse).
