Improper Limitation of a Pathname to a Restricted Directory ('Path Traversal')

CVE-2024-1560

High
8.1/10

Summary

A path traversal vulnerability exists in the mlflow, specifically within the artifact deletion functionality. Attackers can bypass path validation by exploiting the double decoding process in the '_delete_artifact_mlflow_artifacts' handler and 'local_file_uri_to_path' function, allowing for the deletion of arbitrary directories on the server's filesystem. This vulnerability is due to an extra unquote operation in the 'delete_artifacts' function of 'local_artifact_repo.py', which fails to properly sanitize user-supplied paths. The issue affects mlflow, despite attempts to fix a similar issue in CVE-2023-6831.

CWE-22 - Path Traversal

Path traversal (or directory traversal), is a vulnerability that allows malicious users to traverse the server's root directory, gaining access to arbitrary files and folders such as application code & data, back-end credentials, and sensitive operating system files. In the worst-case scenario, an attacker could potentially execute arbitrary files on the server, resulting in a denial of service attack. Such an exploit may severely impact the integrity, confidentiality, and availability of an application.
