CVE-2025-47819Public exploit

Firmware extraction and modification via enabled JTAG

Published Jun 27, 2025 · Updated Sep 2, 2025

Improper access control in Flock Safety Gunshot Detection devices before 1.3 allows physically proximate attackers to alter firmware. The ESP32 has JTAG and UART download mode enabled, leaving their disable fuses unset and permitting firmware extraction or replacement through exposed board pads. Exploitation requires opening the pole-mounted sensor, wiring its debug pads, and using device-debugging hardware; the vendor reports no effect on its cloud platform.
