Low risk32th percentile - higher than 32% of all known CVEs
Summary
DJI drones contain an FTP service with hardcoded credentials shared across affected models, allowing authenticated users to upload files without limits and overwrite files in **/blackbox/upgrade/**. An attacker with network or USB RNDIS access can exhaust storage, preventing flight records and firmware updates. Uploaded files persist across reboot and factory reset.
Risk Assessment
An attacker can permanently impair drone functionality, preventing data logging and updates, potentially leading to loss of control or operational security issues.
Recommendation
Install the firmware update provided by the vendor for affected DJI drone models.
Original NVD description (English source)
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.
