Upgrade from old firmware, is it safe?

/system routerboard print                                          
       routerboard: yes

I was neglecting this box a bit and I would like to ask if it is safe to upgrade + do I need to upgrade routerboard first or os, or both are upgraded automatically / doesn't matter?

(Yeah I know there was exploit, I am not crazy to have management ports open to internet ;) )

it's still a supported device.
Before you upgrade: "/export compact" your full config + export any certificates / keys you have in use, as these are not part of "export"
you're bridge config will change, so be careful with restore if needed.

BootRom can be updated after software update.

He detectado un nuevo tipo de ataque en donde editan el factory firmware poniendo una versión mas reciente que el upgrade Firmware entonces el MK no se actualiza y mientras tanto persiste la versión de Firmware vulnerable.

Se les ocurre que hacer?

Factory Firmware: 3.41
Current Firmware: 3.41
Upgrade Firmware: 3.33
