EVE's Debug Functions Unlockable Without Triggering Measured Boot
### Impact On boot, Pillar checks for /config/GlobalConfig/global.json and overrides system configuration if present. This allows enabling debug functions like SSH (debug.enable.ssh), USB keyboard (debug.enable.usb), and VNC access (app.allow.vnc) without triggering the measured boot. Thus, a user with physical access can take out the disk and modify the content of this file in the /config partition and then re-insert the disk. ### Patches Fixed in 10.1.0 and 9.4.3-lts ### Workarounds None
