CVE-2026-114353
HighCVSS 7.0Summary
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().
Risk Assessment
An attacker with physical USB access can achieve arbitrary command execution as root, leading to full device compromise. This could result in backdoor installation, data theft, or persistent system damage.
Recommendation
Update DJI CrystalSky ZS600C firmware to a version later than v0.6.6.9 if available, or contact the vendor. Restrict physical USB access to the device and monitor for unusual activity.
Other vulnerabilities in DJI CrystalSky ZS600C firmware
See all- CVE-2026-114356High
Missing authorization in the system-privileged 'DJIUpdateService' binder in DJI CrystalSky ZS600C firmware v0.3.9.7 through v0.6.6.9 on Android allows a local application with no permissions to invoke privileged operations, including factory reset with user-data wipe (transaction 153), shutdown (105), clock/timezone change (101/123), and the firmware-apply hand-off (151), because onTransact() performs no caller-identity or permission check.
- CVE-2026-114355High
OS command injection in the root-privileged 'hardware_monitor' helper in DJI CrystalSky ZS600C firmware v0.3.9.7 through v0.6.6.9 on Android allows a local unprivileged process to execute arbitrary commands as root by writing a crafted line to the Android log (logcat), which the helper reads and passes to a shell eval.
- CVE-2026-114354High
Missing authorization in the native binder service 'android.dji.server' (transaction code 1018) in DJI CrystalSky ZS600C firmware v0.3.9.7 through v0.6.6.9 on Android allows a local application with no permissions to execute arbitrary OS commands as root, because the handler passes a caller-supplied string to system() in the root-privileged 'assistant' daemon without any caller-identity or permission check.
