Apache IoTDB: Missing authentication for critical function
Summary
Apache IoTDB versions 2.0.0 up to 2.0.10 contain a missing authentication check for a critical function (CWE-306). The CNA rates the issue at CVSS 9.8 (critical), and the vector indicates it is reachable over the network without privileges or user interaction. The official description does not name the affected component or the exact impact; the mailing-list subject mentions remote code execution and unauthenticated path traversal, which is not yet confirmed. Instances reachable from untrusted networks are at the highest risk.
Affected
- Apache IoTDB 2.0.0 up to, but not including, 2.0.11 (i.e. 2.0.0 to 2.0.10)
- Versions 1.x: Unknown. Confirm with Apache.
Fixed in
- Apache IoTDB 2.0.11
Workaround
- No vendor workaround published.
- Restrict network access to IoTDB ports to known clients and administrator hosts until 2.0.11 is installed (own recommendation, not vendor-stated).
Exploitation
- Known exploitation in the wild: none found. Not listed in KEV according to Strix; this is not proof of no exploitation.
- Public proof of concept: not confirmed for this CVE.
- CISA SSVC: exploitation none, automatable yes, technical impact total.
Our recommendation
- Inventory all IoTDB instances and versions, including Docker and embedded deployments.
- Upgrade 2.0.x instances to 2.0.11 as a priority, especially those reachable from outside the local network.
- Restrict access to IoTDB ports now, until the upgrade is complete.
- Review logs for unexpected connections or configuration changes.
- Check NVD and the Apache advisory for updates to the score and affected components.
Public exploits
PoC-in-GitHub, Metasploit and Exploit-DB list nothing for this CVE.
