PCN Information:
Description:A vulnerability of the RX65N has been reported whereby ID-protected on- chip flash memory contents can be read by means of a voltage fault injection attack. The attack requires physical access to the target device and modification of the circuit board to operate the outside of recommended conditions; specifically, removing any power pins capacitors on the PCBboard assembly, and performing targeted voltage glitches on the microcontroller VCLpin. This vulnerability is identified as CVE-2021-43327.AffectedProducts:Fault injection attacks were considered out of scope when the current RX Family MCU products were originally released, as was standard for general purpose MCUs. The vulnerability analysis results from this issue are being used to consider how Renesas can enhance the robustness of future RXFamily MCU products against such attacks.Mitigation:Since physical access to the target deviceis required, preventing physical accessor detecting and responding to enclosure breaches are countermeasures for this fault injection attack. To reduce the potential consequences of this type of attack, some RX Family products include Trusted Secure IP and Trusted Secure IPLite, which support secures to rage of cryptographic keys.
