Description
Missing authentication for a critical function in the Android Debug Bridge daemon (adbd) in DJI CrystalSky ZS600C firmware v0.3.9.7 through v0.6.6.9 allows an attacker to obtain an unauthenticated shell (uid 2000), a foothold for privilege escalation to root. The device ships with ro.adb.secure=0 (no host key authorization) and USB ADB enabled by default; ADB over TCP is not enabled by default but, once enabled (e.g. via the shipped /system/bin/adbd_tcp.sh or 'setprop persist.adb.tcp.port 5555'), the same unauthenticated shell is reachable over the network (CVSS 4.0 base 9.3).
