Main Content
Introduction
The Gardyn Home Kit, a popular smart gardening system, has been found to contain four critical vulnerabilities that could allow attackers to seize control of devices, steal sensitive information, and compromise connected systems. These flaws, identified in the firmware, mobile application, and cloud API, pose significant risks to users in the Food and Agriculture sector, particularly in the United States. Immediate action is required to patch affected systems and prevent potential exploitation.

Key Points
- Unauthenticated Access: Vulnerabilities allow attackers to bypass authentication and gain control of Gardyn Home Kit devices.
- Command Injection: One flaw enables arbitrary command execution on target devices, granting full system control.
- Credential Theft: Hard-coded and default credentials can be extracted, exposing administrative access.
- Cloud Compromise: Attackers could access cloud-based devices and user data without authentication.
- Mitigation: Gardyn has released updates for firmware, mobile apps, and cloud APIs—users must install them immediately.

Technical Details
#### Affected Systems
The following Gardyn Home Kit components are impacted:
- Firmware: Versions prior to `master.619`
- Mobile Application: Versions below `2.11.0`
- Cloud API: Versions below `2.12.2026`
#### Vulnerability Breakdown
1. CVE-2025-29628 (CVSS 8.3 - High)
- Type: Cleartext Transmission of Sensitive Information
- Description: An Azure IoT Hub connection string is transmitted over insecure HTTP, making it vulnerable to Man-in-the-Middle (MitM) attacks. Attackers could intercept or modify the string to capture device credentials or take control of home kits.
- Impact: Unauthorized access to devices and cloud environments.
2. CVE-2025-29629 (CVSS 8.3 - High)
- Type: Use of Default Credentials
- Description: The Gardyn Home Kit uses weak default credentials for secure shell (SSH) access. Attackers could exploit this to gain unauthorized access to exposed devices.
- Impact: Full control of vulnerable home kits.
3. CVE-2025-29631 (CVSS 9.1 - Critical)
- Type: OS Command Injection
- Description: The system fails to sanitize user input before executing commands, allowing attackers to inject arbitrary OS commands and execute them on target devices.
- Impact: Remote code execution (RCE) and full system compromise.
4. CVE-2025-1242 (CVSS 9.1 - Critical)
- Type: Use of Hard-coded Credentials
- Description: Administrative credentials can be extracted through API responses, mobile app reverse engineering, or firmware analysis. Attackers could gain full administrative access to the IoT Hub and connected devices.
- Impact: Complete control over Gardyn Home Kit systems and connected devices.

Impact Assessment
The vulnerabilities in the Gardyn Home Kit pose severe risks, including:
- Unauthorized Device Control: Attackers could manipulate gardening systems, disrupt operations, or cause physical damage.
- Data Theft: Sensitive user information stored in the cloud could be accessed and exfiltrated.
- Lateral Movement: Compromised devices could serve as entry points to broader networks, including home or enterprise environments.
- Supply Chain Risks: As a Food and Agriculture sector device, exploitation could disrupt food production or distribution systems.

Mitigation Steps
Gardyn has released patches to address these vulnerabilities. Users must take the following steps immediately:
1. Update Firmware: Ensure all Gardyn Home Kit devices are running firmware version `master.619` or later.
2. Update Mobile App: Install the latest version of the Gardyn Home Kit mobile app (2.11.0 or higher).
3. Update Cloud API: Verify that the cloud API is updated to version `2.12.2026` or later.
4. Check for Updates: Use the Gardyn app to verify the current firmware and app versions.
5. Ensure Network Connectivity: Devices must be connected to the internet to receive automatic updates. Unconnected devices will update once reconnected.
6. Review Security Best Practices: Visit Gardyn’s [security page](https://mygardyn.com/security/) for additional guidance.

Recommended Practices for IoT Security
To minimize the risk of exploitation, CISA recommends the following best practices:
- Network Segmentation: Isolate IoT devices from business networks using firewalls.
- Limit Exposure: Avoid exposing control systems or IoT devices directly to the internet.
- Secure Remote Access: Use Virtual Private Networks (VPNs) for remote access and ensure they are updated to the latest version.
- Monitor for Malicious Activity: Implement intrusion detection systems (IDS) to identify and respond to suspicious activity.
- Regular Updates: Keep all software, firmware, and applications up to date with the latest security patches.
For more details, refer to CISA’s [ICS Cybersecurity Best Practices](https://www.cisa.gov/ics).

Conclusion
The Gardyn Home Kit vulnerabilities highlight the critical importance of securing IoT devices, particularly in sectors like Food and Agriculture. While Gardyn has released patches, users must act swiftly to update their systems and protect against potential attacks. As IoT adoption grows, manufacturers and users alike must prioritize cybersecurity to prevent exploitation and safeguard sensitive data.
