Critical Authentication

CVE-2026-114357 — DJI CrystalSky ZS600C ships ADB without authentication (ro.adb.secure=0)

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).

Who exploits it and how urgent it is

A 0–100 score combining confirmed exploitation, ransomware and APT use, public exploits, EPSS and severity.

No exploitation signal in the sources consulted so far.
How the score was calculated
  • EPSS 0.3% (30-day exploitation probability)+4
  • Technical severity (critical)+10

The score orders the patch queue; it does not replace your asset context (internet exposure, criticality, compensating controls).

Triage

Is it exploited, how likely is exploitation, what does it touch, and how severe do the sources call it.

Remediation

Fixes and mitigations documented by the sources — linked to the original advisory.

No fix documented by the sources we poll. That does not mean none exists: check the vendor advisory.

First 24 hours

Ordered from the record’s own fields — exposure first, because you cannot patch what you have not found. A rule-generated starting point.

  1. Identify exposed assets running the affected vendor/product/version combinations (DJI CrystalSky ZS600C).
  2. The attack is network-based and needs no privileges: restrict exposure (ACLs, VPN, WAF) until patched.
  3. No fix documented in the sources: reduce exposure and monitor the vendor advisory.
  4. Search available logs for exploit probes matching the vulnerability class (authentication), errors and authentication anomalies.

Detection

Read off the CVSS vector and the weakness class. Starting points, not tested rules.

  • Prioritize edge telemetry for the network-reachable component (proxy, WAF, IDS/IPS).
  • Review authentication logs: logins without MFA, anomalous sessions and recently created accounts.
