CVE-2026-52481Public exploit

Root command execution via unauthenticated TCP backdoor

Published Aug 18, 2026 · Updated Aug 19, 2026

OS command injection in SJRC F11 SJ-GPS-PRO firmware build 2019-09-17 allows remote attackers to execute commands as root. The /app/vs_play tcp_actions() handler copies the 29 bytes after a da packet prefix into a buffer, passes them directly to system(), and echoes them over TCP port 8888. Access requires joining the drone's unencrypted Wi-Fi network; the command protocol performs no authentication, and successful commands control the device as root.
