id: CVE-2024-2928

info:
  name: MLflow < 2.11.3 - Path Traversal
  author: jyjyjy25,gy741,oriing,ANseunghyeon,woo4826
  severity: high
  description: |
    MLflow versions prior to 2.11.3 are vulnerable to a Path Traversal attack due to improper URI fragment parsing. This vulnerability allows attackers to read arbitrary files on the server, potentially exposing sensitive information.
  impact: |
    Successful exploitation could allow an attacker to read arbitrary files such as /etc/passwd in the local file system.
  remediation: |
    Upgrade MLflow to version 2.11.3 or later to mitigate this issue.
