Summary

CVE-2024-3848 is a high-severity Path Traversal: '\..\filename' (CWE-29) vulnerability in Lfprojects Mlflow. Its CVSS base score is 7.5 (High).

Operationally, exploitation aligns with the MITRE ATT&CK technique Exploit Public-Facing Application (T1190); ranked in the top 1% of CVEs by exploit likelihood; it is not currently listed in the CISA KEV catalog; a public proof-of-concept is referenced.

This vulnerability is AI-related — categorised as Other AI Platforms; in the Privacy and Disclosure risk domain.

The strongest mitigations our analysis identified map to AC-3 (Access Enforcement) and SI-10 (Information Input Validation) — see the control section below for these in your framework.

Synthesised by an AI model from the NVD description and linked references — a reading aid, not an authoritative source.

MLflow version 2.11.0 contains a path traversal vulnerability, CVE-2024-3848, that bypasses the earlier fix for CVE-2023-6909. The flaw lies in the handling of artifact URLs: a “#” character places an attacker-controlled path in the URL fragment, causing the application to skip protocol-scheme validation and convert the fragment directly into a filesystem path.

An unauthenticated remote attacker can therefore supply a crafted artifact URL that results in arbitrary file reads on the server, including SSH keys and cloud credentials. The vulnerability is rated CVSS 7.5 with network attack vector, low complexity, and high confidentiality impact.

The referenced commit f8d51e21523238280ebcfdb378612afd7844eca8 in the mlflow repository applies the corrective validation of URL fragments. The associated EPSS score is currently 0.7610 and reached a peak of 0.7952.

Vulnerability Data

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.

Mitigating Controls (NIST 800-53 r5) AI

Enforces the intended directory access authorizations that path traversal would otherwise bypass.

Input validation directly neutralizes the '\..\filename' sequence before pathname resolution occurs.

Least privilege reduces the impact of any unauthorized file access obtained via traversal.

PR.PS-06 mostly match
prevents

Secure SDLC practices directly require input validation and path sanitization that block this traversal vector.

PR.PS-02 partial match
prevents

Patching/maintenance can remediate known path-traversal flaws in deployed software (partial prevention of exploitability) but does nothing to stop the coding defect from being introduced in the first place.

PR.AA-05 none match
prevents

PR.AA-05 defines and reviews access policies but does not address code-level pathname neutralization, so neither direction prevents CWE-22.

finds

Security testing can discover path-traversal flaws but does not itself prevent them in production code.

prevents

Secure SDLC mandates input validation and path sanitization that directly prevent path traversal.

prevents

Application security requirements can mandate input validation and path canonicalization to block traversal sequences.

prevents

Secure architecture principles include directory sandboxing and safe file-access design that mitigate path traversal.

prevents

Secure coding standards directly require neutralizing path traversal sequences such as '\..\filename'.

mitigates

Information access restriction limits which files an application may read or write.
