DJI drones expose an unauthenticated DUML command interface over Bluetooth that allows an attacker within Bluetooth range to modify Wi-Fi configuration parameters, including the SSID, PSK, MAC address, regulatory country code, and wireless channel. An attacker can overwrite the Wi-Fi PSK with a known value and connect to the drone's internal Wi-Fi network, potentially gaining access to the flight control interface and issuing flight commands. Crafted DUML commands can also disable or restart the Wi-Fi and Bluetooth interfaces, disconnect Wi-Fi clients, or reset wireless configuration, resulting in a denial-of-service condition that can disrupt the operator's wireless control, video, and telemetry connections during flight.

Affected models are DJI Neo until 01.00.0400, DJI Neo 2 until 01.00.0500, DJI Flip until 01.00.1200, DJI Air 3 until 01.00.1600, DJI Air 3S until 01.00.1400, DJI Avata 2 until 01.00.0400, DJI Avata 360 until 01.00.0300, DJI Mavic 3 until 01.00.1400, DJI Mavic 3 Classic until 01.00.0800, DJI Mavic 3 Pro until 01.01.0700, DJI Mavic 4 Pro until 01.00.0500, DJI Mini 2 until 01.07.0200, DJI Mini 3 until 01.00.0500, DJI Mini 3 Pro until 01.00.0900, DJI Mini 4 Pro until 01.00.1100, and DJI Mini 5 Pro until 01.00.0600.

Remediation requires a firmware update from the vendor.
