CVE-2026-52480

Information disclosure via unauthenticated inetd-spawned FTP

Published Aug 18, 2026 · Updated Aug 19, 2026

Information disclosure in SJRC F11 SJ-GPS-PRO firmware build 2019-09-17 allows remote attackers to retrieve device files over FTP. The inetd configuration spawns /sbin/ftpd on TCP port 21 without authentication, exposing firmware and other files to any FTP client. Access requires joining the drone's open Wi-Fi network, so the consequence is bounded to reading files available through the service.
