MEDIUM NUCLEI

MLflow < 2.9.0 - Reflected Cross-Site Scripting via Content-Type Header

Title source: llm
STIX 2.1

Exploitation Summary

CVE-2023-6568 has a Nuclei detection template available — see the Nuclei card below for the Shodan/FOFA recon queries.

Description

A reflected Cross-Site Scripting (XSS) vulnerability exists in the mlflow/mlflow repository, specifically within the handling of the Content-Type header in POST requests. An attacker can inject malicious JavaScript code into the Content-Type header, which is then improperly reflected back to the user without adequate sanitization or escaping, leading to arbitrary JavaScript execution in the context of the victim's browser. The vulnerability is present in the mlflow/server/auth/__init__.py file, where the user-supplied Content-Type header is directly injected into a Python formatted string and returned to the user, facilitating the XSS attack.
