Want to hear some more scary **** ?
The GUI in FortiClient is a small webserver, so the functions are plain javascript.
As a normal user (no admin), take a copy of the forticlient.exe file, put it on your desktop.
Edit the file with Notepad++
Because forticlient contains javascript, the functions are in plain text.
Find the password function. it will be something like this: "if password == password2 then bla bla"
change the "==" to "!="
Save the file
Run it from the desktop, click on disconnect, enter any password you like, BOOM!! accepted and disconnected......
