  • CVE-2024-2635: The configuration pages available are not intended to be placed on an Internet facing web server, as they expose file paths to the client, who can be an attacker.

  • CVE-2024-2636: The Meta4 HR system administrator should remove the following pages from the web servers facing the Internet: From M4WebServices: The folder "config" (containing the webappconfig.jsp page).
