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.Show less

A vulnerability in the web-based management interface of Cisco Firepower Management Center (FMC) Software could allow an unauthenticated, remote attacker to access sensitive information. This vulnerability is due to missing authorization for certain resources in the web-based management interface together with insufficient entropy in these resource names. An attacker could exploit this vulnerability by sending a series of HTTPS requests to an affected device to enumerate resources on the device. A successful exploit could allow the attacker to retrieve sensitive information from the device.Show less
