DJI drones contain an FTP service that uses hardcoded credentials shared across affected models and permits authenticated users to upload files without limits on file size, file count, or total storage consumed in **/blackbox/upgrade/**, as well as overwrite existing files in that directory. An attacker with access to the drone's internal network or USB RNDIS interface can exhaust the available storage, preventing the aircraft from writing flight records, logs, and telemetry and potentially preventing subsequent firmware updates. Uploaded files persist across reboot and factory reset.
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.
