Executive Summary
In February 2026, multiple critical vulnerabilities were identified in the Gardyn Home Kit, an AI-powered indoor gardening system. These flaws included insecure credential exchange (CVE-2025-29628), weak default SSH credentials (CVE-2025-29629), command injection vulnerabilities (CVE-2025-29631), and API credential leakage (CVE-2025-1242). Exploitation could have allowed unauthenticated users to remotely control devices, access user information, and pivot to other devices within the Gardyn cloud environment. Gardyn promptly addressed these issues by releasing firmware updates and advising users to ensure their devices were connected to the internet to receive automatic updates. (mygardyn.com)
This incident underscores the growing security challenges in IoT devices, particularly those integrated into personal living spaces. The vulnerabilities highlight the importance of robust security practices in the development and maintenance of smart home technologies to prevent unauthorized access and potential data breaches.
Why This Matters Now
The Gardyn Home Kit vulnerabilities highlight the urgent need for enhanced security measures in IoT devices, especially as smart home technologies become more prevalent. Ensuring timely updates and robust security protocols is crucial to protect user data and prevent unauthorized access.
Attack Path Analysis
An attacker exploited the Gardyn Home Kit's vulnerabilities, starting with intercepting unencrypted Azure IoT Hub connection strings to gain unauthorized access. They then escalated privileges by leveraging default SSH credentials and hard-coded administrative credentials. Using command injection flaws, the attacker moved laterally to other devices within the Gardyn cloud environment. They established command and control by executing arbitrary code remotely. Subsequently, they exfiltrated sensitive user information and device data. Finally, the attacker could manipulate device operations, potentially disrupting plant growth or causing physical damage.
