• → POST requests to /CDGServer3/ClientAjax with body parameter 'command=downclientpak' indicate exploitation of CVE-2019-9632 arbitrary file download.
• → HTTP 200 response containing the string 'CDGPermissions' in the body confirms successful arbitrary file read via the InstallationPack path traversal parameter.
• → FOFA query 'title="电子文档安全管理系统"' can be used to identify exposed ESAFENET CDG instances on the internet.
