a strange thing happened to me today.
My home firewall 40F (7.2.1) rebooted unexpectedly.
I looked in the log and found that the reboot was done by the user "fortigate-tech-support" and the reason was a firmware upgrade (7.2.1->7.2.2)
In system/Administrator this user was created and I don't know about it.
My admin password is set to 17 characters (including special characters) and another administrator has an equally strong password.
FortiGate is added to FortiCloud.
Passwords remained unchanged, all configuration looks ok.
How should I explain it? I'm assuming it's not a trusted event... or is it something to do with the new CVE?
