CVE-2026-29988: High severity Milesight IoT devices (NFC interface) vulnerability
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.

Frequently Asked Questions
Who is exposed to exploitation?
Milesight IoT devices with an NFC interface that are running affected firmware versions are exposed. Exploitation requires an attacker to be in physical proximity to perform an NFC read operation.
What does an attacker need to exploit this issue?
No authentication, user interaction, or prior privileges are required. The attacker needs physical proximity to the device and the ability to read its NFC interface.
What could an attacker do with the exposed keys?
An attacker can retrieve LoRaWAN ABP NwkSKey and AppSKey values and D2D keys. These keys can enable LoRaWAN traffic decryption, forged uplink or downlink frames, falsified sensor data submission, supported device commands, and rejection of later legitimate frames.
