Severity
7.0 (High) - CVSS:4.0/AV:P/AC:L/AT:N/PR:N/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N/S:P
Summary
Hidden functionality (undocumented backdoor) in the root-privileged 'assistant' daemon in DJI CrystalSky ZS600C firmware v0.3.9.7 through v0.6.6.9 on Android allows a physically-present attacker with USB access to execute arbitrary OS commands as root by sending the hard-coded magic string 'dji26656677' to the USB-gadget serial interface (/dev/ttyGS0), after which each subsequent line is passed to system().
