CVE-2024-3848

HIGH NUCLEI

MLflow < 2.12.1 - Path Traversal via URL Fragment Bypass

Title source: llm
STIX 2.1

Exploitation Summary

CVE-2024-3848 has a Nuclei detection template available — see the Nuclei card below for the Shodan/FOFA recon queries.

Description

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.
