DJI CrystalSky ZS600C: Command injection as root via Android binder service
Summary
The native binder service android.dji.server on the DJI CrystalSky ZS600C in firmware v0.3.9.7 through v0.6.6.9 accepts a string from any calling app without an identity or permission check and passes it to system() in a root-privileged daemon. A locally installed app with no permissions can therefore execute arbitrary operating system commands as root. Exploitation requires a malicious or compromised app on the device; no public proof of concept or known exploitation was found.
Affected
- DJI CrystalSky ZS600C, firmware v0.3.9.7 through v0.6.6.9 (Android)
- Source records differ on whether 0.3.9.7 is affected by default; treat the whole range as affected until DJI or the CNA clarifies.
Fixed in
Unknown. No DJI security advisory or firmware fix was found. The device is reported as end-of-life and unsupported.
Workaround
- No vendor-documented workaround known.
- Allow only trusted, managed apps and remove unneeded apps.
- Restrict physical and USB access to the device.
- Keep the device off company networks where possible.
Exploitation
- Not known exploited; not listed in CISA KEV.
- No public proof of concept found; this does not prove none exists.
- EPSS 0.0013 (low).
- CISA SSVC: exploitation none, automatable no, technical impact total.
- Related sibling CVEs in the same firmware range may be chained for root access.
Our recommendation
- Inventory all ZS600C units and identify who uses them and which apps they run.
- Treat the devices as untrusted endpoints until DJI publishes a fix.
- Remove unneeded apps and restrict app installation and physical/USB access.
- Plan replacement, as the device is end-of-life.
- Recheck NVD and DJI support pages for updates.

PoC-in-GitHub, Metasploit and Exploit-DB list nothing for this CVE.

Original description (NVD)
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.
