CVE-2019-3944Public exploit

Flight-control interruption via forged Wi-Fi deauthentication frames

Published Apr 1, 2020 · Updated Aug 4, 2024

Denial of service in Parrot ANAFI firmware before 1.5.0 allows remote attackers to sever the drone-controller link with Wi-Fi deauth frames. The wireless link processes forged deauthentication management frames without authenticating their sender, terminating the active controller association. An attacker must be within Wi-Fi range; a successful attack interrupts live control and invokes Smart Return to Home rather than crashing the aircraft.
