JFinalCMS v5.0.0 - Directory Traversal

id: CVE-2023-41599

info:
  name: JFinalCMS v5.0.0 - Directory Traversal
  author: pussycat0x
  severity: medium
  description: |
    An issue in the component /common/DownController.java of JFinalCMS v5.0.0 allows attackers to execute a directory traversal.
  impact: |
    Unauthenticated attackers can read arbitrary files from the server through path traversal in the filekey parameter, potentially exposing database credentials, application configuration, and sensitive CMS content.
  remediation: |
    Update JFinalCMS to a version newer than 5.0.0 that validates and sanitizes file paths in DownController.java to prevent directory traversal attacks.
