A Use of Weak Credentials vulnerability affecting the Wi-Fi network generated by a set of DJI drones could allow a remote attacker to derive the WPA2 PSK key and authenticate without permission to the drone’s Wi- Fi network. This, in turn, allows the attacker to perform unauthorized interaction with the network services exposed by the drone and to potentially decrypt the Wi-Fi traffic exchanged between the drone and the Android/IOS device of the legitimate user during QuickTransfer mode. Affected models are Mavic 3 Pro until v01.01.0300, Mavic 3 until v01.00.1200, Mavic 3 Classic until v01.00.0500, Mavic 3 Enterprise until v07.01.10.03, Matrice 300 until v57.00.01.00, Matrice M30 until v07.01.0022 and Mini 3 Pro until v01.00.0620.
The number of possible random values is smaller than needed by the product, making it more susceptible to brute force attacks.
