WAGO: Early-Boot Diagnostic Exposure in WAGO System I/O Field Devices
Risk evaluation
Certain devices in the WAGO System I/O Field series enable an internal diagnostic capability during the initial stages of system startup. This behavior, which is not part of the publicly documented feature set, briefly allows access to system functions before the main operating environment becomes fully active. Under specific conditions, this could permit interactions with system components that are normally protected during regular operation.
