CVSS v3 6.3

ATTENTION: Remotely exploitable/low skill level to exploit.

Vendor: CyberVision

Equipment: Kaa IoT Platform

Vulnerability: Code Injection


The following version of Kaa IoT Platform, a middleware platform, is affected:

  • Kaa IoT Platform, Version 0.7.4, and possibly other versions.


Successful exploitation of this vulnerability could allow for the creation of files with custom content, movement of files, and execution of arbitrary OS commands.


CyberVision’s Kaa Project has been unresponsive to multiple contact requests and has produced no mitigations for this vulnerability.

NCCIC/ICS-CERT recommends that users take defensive measures to minimize the risk of exploitation of this vulnerability. Specifically, users should:

  • Minimize network exposure for all control system devices and/or systems, and ensure that they are not accessible from the Internet.
  • Locate control system networks and remote devices behind firewalls, and isolate them from the business network.
  • When remote access is required, use secure methods, such as Virtual Private Networks (VPNs), recognizing that VPNs may have vulnerabilities and should be updated to the most current version available. Also recognize that VPN is only as secure as the connected devices.

ICS-CERT reminds organizations to perform proper impact analysis and risk assessment prior to deploying defensive measures.

ICS-CERT also provides a section for control systems security recommended practices on the ICS-CERT web page. Several recommended practices are available for reading and download, including Improving Industrial Control Systems Cybersecurity with Defense-in-Depth Strategies.

Additional mitigation guidance and recommended practices are publicly available in the ICS‑CERT Technical Information Paper, ICS-TIP-12-146-01B--Targeted Cyber Intrusion Detection and Mitigation Strategies, that is available for download from the ICS-CERT web site.
