| Description | Finding 3: Firmware Version Check Manipulation and UI Spoofing
The mobile app does not validate firmware version responses during update checks. There is no signature checks, though the mobile app reflects that check to be being done.
An attacker can intercept and modify this response to display an arbitrary “newer” version, enabling the upgrade button even when the device is up to date.
This allows UI spoofing and misleading update prompts.
