View CSAF Successful exploitation of these vulnerabilities could allow unauthenticated users to access and control IoT Hub managed devices. The following versions of Gardyn IoT Hub are affected: Expand All + Gardyn devices expose a privileged iothubowner key. Access to this key will allow a malicious user to invoke an IoTHub Registry Manager function which returns connection information for all Gardyn Home Kit and Studio devices. Access to this key also allows a malicious user to execute arbitrary commands on a specific connected device and may allow the malicious user to pivot to other devices on the user's network. View CVE Details MitigationGardyn states that IoT Hub deployed infrastructure has been updated to fix the listed vulnerabilities. MitigationGardyn requests that users ensure their devices have Internet connectivity in order to automatically download needed firmware updates. Unconnected devices will automatically update when configured with a working Internet connection. Gardyn also recommends that users update their mobile application to the most recent version. The current versions of the Gardyn App and the Gardyn Home firmware can be checked in the Gardyn App. MitigationFurther information on Gardyn security can be found here: https://mygardyn.com/security/https://mygardyn.com/security/ MitigationFurther customer support can be obtained from Gardyn at: support@mygardyn.commailto:support@mygardyn.com Relevant CWE:CWE-798 Use of Hard-coded Credentials The Azure Blob Storage container used for Gardyn device logs is publicly listable without authentication.

CISA recommends users take defensive measures to minimize the risk of exploitation of these vulnerabilities. Minimize network exposure for all control system devices and/or systems, ensuring they are not accessible from the Internet. Locate control system networks and remote devices behind firewalls and isolating them from business networks. When remote access is required, use more secure methods, such as Virtual Private Networks (VPNs), recognizing VPNs may have vulnerabilities and should be updated to the most current version available. Also recognize VPN is only as secure as the connected devices. CISA reminds organizations to perform proper impact analysis and risk assessment prior to deploying defensive measures. CISA also provides a section for control systems security recommended practices on the ICS webpage on cisa.gov/ics. Several CISA products detailing cyber defense best practices are available for reading and download, including Improving Industrial Control Systems Cybersecurity with Defense-in-Depth Strategies. CISA encourages organizations to implement recommended cybersecurity strategies for proactive defense of ICS assets. Additional mitigation guidance and recommended practices are publicly available on the ICS webpage at cisa.gov/ics in the technical information paper, ICS-TIP-12-146-01B--Targeted Cyber Intrusion Detection and Mitigation Strategies. Organizations observing suspected malicious activity should follow established internal procedures and report findings to CISA for tracking and correlation against other incidents. No known public exploitation specifically targeting these vulnerabilities has been reported to CISA at this time.
