4th percentile - higher than 4% of all known CVEs

Summary

A cleartext transmission of sensitive information vulnerability in the NFC interface of multiple Milesight IoT device models running affected firmware versions allows an unauthenticated attacker with physical proximity to retrieve LoRaWAN ABP NwkSKey and AppSKey values and D2D keys via an NFC read operation. The exposed keys can be used to decrypt LoRaWAN traffic, forge uplink and downlink frames, submit falsified sensor data, issue supported device commands, and cause subsequent legitimate frames to be rejected.

Risk Assessment

Risk of interception and manipulation of LoRaWAN data, potentially leading to data integrity violation, false readings, and unauthorized device control.

Recommendation

Update Milesight device firmware to a version that encrypts NFC transmission or disables key access via NFC, and restrict physical access to devices.
