Missing Authentication in FortiManager (CVE 2024-47575)

I propose to write a case study about a serious security bug in Fortinet FortiManager called CVE-2024-47575. This bug let hackers take control of FortiManager systems without needing a password. It's a "missing authentication" vulnerability, which means the software forgot to check if someone was allowed to do something important.

Starting in June 2024, cybercriminals exploited this flaw to compromise over 50 FortiManager systems and steal sensitive configuration data including passwords and network layouts. The vulnerability happened because FortiManager was set to automatically accept and register any new device without checking if it was actually authorized, a classic example of missing authentication (CWE-306).

My case study will focus on practical prevention strategies that developers can immediately apply. I will explain how to implement proper authentication checks before critical operations, why "deny by default" configurations are essential (requiring admin approval instead of automatic registration), and how multiple security layers like IP whitelisting and (if possible) certificate validation provide defense in depth.

Start by reading the linked NVD, CISA, and Rapid7 references to verify the CVE details and timeline. Compare the findings with the repository's existing secure-coding case studies, then produce a case study covering missing authentication, deny-by-default configuration, and layered defenses; done means the documented prevention guidance is supported by the cited sources.
