Executive Summary

This vulnerability involves a Denial of Service (DoS) attack on Parrot AR.Drone 1 and AR.Drone 2 platforms. It allows remote and unauthenticated attackers to disconnect the drone from its controller during flight by exploiting a Wi-Fi deauthentication attack.

Detection Guidance

This vulnerability involves a Wi-Fi deauthentication attack on Parrot AR.Drone 1 and 2. Detection may involve monitoring for unusual disconnections or analyzing Wi-Fi traffic for deauthentication frames. Use tools like Wireshark to capture and inspect Wi-Fi packets for deauthentication frames targeting the drone's MAC address.

Impact Analysis

This vulnerability could cause loss of control over the drone during flight, leading to crashes or unintended behavior. It may result in physical damage to the drone or surrounding property and poses safety risks during operation.

Mitigation Strategies

To mitigate this vulnerability, avoid using Parrot AR.Drone 1 and 2 in environments with untrusted Wi-Fi networks. Ensure the drone's firmware is updated if patches are available. Use strong Wi-Fi encryption and consider disabling Wi-Fi when not in use to reduce exposure to deauthentication attacks.
