Neo: Use of Hard-coded Credentials

Published Updated By the CyberSecBulletin desk

CVE-2026-78251 is a critical-severity use of hard-coded credentials vulnerability in Neo from DJI, with a CVSS 4.0 base score of 9.3 out of 10. It can be exploited remotely over the network by an unauthenticated attacker, without any action from a user. Affected Neo versions: 01.00.0400 and earlier. The record does not name a fixed version, so check the vendor advisory. There is no confirmed exploitation so far. EPSS estimates a 0.41% chance of exploitation within 30 days, which is low compared with other CVEs.

Critical severity: a successful attack would have severe impact.

What to do

  1. Check which version of Neo you run against the affected versions below, and install the vendor's latest release.
  2. Until you can update, restrict network access to the affected service so it is not reachable from untrusted networks.

Official description

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.

The underlying weakness: Use of Hard-coded Credentials

The product contains hard-coded credentials, such as a password or cryptographic key.

How developers prevent this class of flaw

  • For outbound authentication: store passwords, keys, and other credentials outside of the code in a strongly-protected, encrypted configuration file or database that is protected from access by all outsiders, including other local users on the same system. Properly protect the key (CWE-320). If you cannot use encryption to protect the file, then make sure that the permissions are as restrictive as possible. In Windows environments, the Encrypted File System (EFS) may provide some protection.
  • For inbound authentication: Rather than hard-code a default username and password, key, or other authentication credentials for first time logins, utilize a first login mode that requires the user to enter a unique strong password or key.
  • If the product must contain hard-coded credentials or they cannot be removed, perform access control checks and limit which entities can access the feature that requires the hard-coded credentials. For example, a feature might only be enabled through the system console instead of through a network connection.
