What it is

🔥 A crafty request is all it takes to exploit this gaping hole in Fortinet FortiNAC! Think of it like a restaurant where anyone can send a fake order to the kitchen, and the chef cooks up whatever they’re asked for, without checking the source. That's how this deserialization issue works—an attacker can slip in their own commands via inter-server communication! An attacker could execute unauthorized code or commands, potentially taking full control of your system. This means they could sneak in malware, alter your configurations, or even delete critical data, making the fallout absolutely devastating!

Put simply

Think of it like a restaurant where anyone can send a fake order to the kitchen, and the chef cooks up whatever they’re asked for, without checking the source. That's how this deserialization issue works—an attacker can slip in their own commands via inter-server communication! This vulnerability arises from the deserialization of untrusted data in Fortinet FortiNAC versions below 7.2.1, 9.4.3, 9.2.8, and all earlier versions of 8.x, allowing remote code execution through specially crafted requests.

What to do

An attacker could execute unauthorized code or commands, potentially taking full control of your system. This means they could sneak in malware, alter your configurations, or even delete critical data, making the fallout absolutely devastating! To protect your systems, upgrade FortiNAC immediately to version 7.2.1 or later, or to the latest stable release in the 9.x series. For versions 8.x, be aware that they won't receive a fix, so consider migrating to a supported version as soon as possible! You've got this! Take these actions, and you'll be on the path to securing your network in no time! 🛡️
