Technical details

The vulnerability is a missing authentication issue (CWE-306) in the inetd service, which spawns an FTP daemon (/sbin/ftpd) on TCP port 21 without requiring credentials. The attack surface is the drone's unencrypted open WiFi access point (172.16.10.1), which assigns DHCP addresses to connected clients. An unauthenticated attacker within WiFi range can access the FTP service and retrieve arbitrary files including firmware images. No authentication or user interaction is required; the inetd service is enabled by default. No patch has been released by the vendor (SJRC), and the issue remains unpatched in firmware build 2019-09-17.
