CVE-2022-46416Public exploit

Service interruption via DHCP lease-pool exhaustion

Published Mar 27, 2023 · Updated Feb 19, 2025

DHCP resource exhaustion in Parrot Bebop firmware 4.7.1 allows remote attackers to block legitimate devices from joining the drone's Wi-Fi network. The onboard DHCP server accepts repeated DISCOVER messages carrying spoofed MAC addresses and allocates its finite address pool to nonexistent clients. Access to the drone's internal Wi-Fi network is required; pool exhaustion prevents the owner's terminal from obtaining an address and reaching drone services.
