| CVSS | Vendor | Equipment | Vulnerabilities |
|---|---|---|---|
| v3 9.1 | Gardyn | Gardyn Home Kit | Cleartext Transmission of Sensitive Information, Use of Default Credentials, Improper Neutralization of Special Elements used in an OS Command (‘OS Command Injection’), Use of Hard-coded Credentials |
Background
- Critical Infrastructure Sectors: Food and Agriculture
- Countries/Areas Deployed: United States
- Company Headquarters Location: United States
Vulnerabilities
CVE-2025-29628
A Gardyn Azure IoT Hub connection string is downloaded over an insecure HTTP connection leaving the string vulnerable to interception and modification through a Man-in-the-Middle attack. This may result in the attacker capturing device credentials or taking control of vulnerable home kits.

Recommended Practices
CISA recommends users take defensive measures to minimize the risk of exploitation of these vulnerabilities, such as:
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.
