Readycheck to confirm it

Mlflow before 2.2.1 is susceptible to local file inclusion due to path traversal \..\filename in GitHub repository mlflow/mlflow. An attacker can potentially obtain sensitive information, modify data, and/or execute unauthorized administrative operations in the context of the affected site.

Impact

Successful exploitation could allow an attacker to read sensitive files on the server.

Fix

Upgrade Mlflow to version 2.2.1 or later to mitigate the vulnerability.

How to confirm it

Send: POST /ajax-api/2.0/mlflow/registered-models/create ; POST /ajax-api/2.0/mlflow/model-versions/create ; GET /model-versions/get-artifact?path=passwd&name=AJAX-API&version={{version}}
Positive when: matches /root:.*:0:0:/ AND status 200
