ICS/OT Security Flaws Exposed in Gardyn Smart Gardens
Remote Hacking Risks in Smart Gardening Devices
CISA has issued a critical advisory about four vulnerabilities in Gardyn smart gardens, highlighting the growing risks in ICS/OT environments. These flaws, discovered by researcher Michael Groberman, could allow attackers to remotely exploit devices without user interaction. The vulnerabilities span from hardcoded credentials to command injection, exposing sensitive data and device control.
Gardyn’s smart gardens, designed for indoor plant cultivation, rely on automated systems like LED lighting and AI monitoring. However, the recent findings reveal that these devices are vulnerable to remote hacking, emphasizing the need for robust ICS/OT security measures.
Key Vulnerabilities and Their Impact
Critical Flaws
- CVE-2025-29631: Command injection vulnerability enabling arbitrary OS commands.
- CVE-2025-1242: Hardcoded admin credentials exposing full device control.
High-Severity Issues
- CVE-2025-29628: Cleartext transmission of data, risking MitM attacks.
- CVE-2025-29629: Default credentials allowing SSH access.
Gardyn confirmed that attackers could alter device settings, access photos, and extract limited personal information. However, no in-the-wild exploitation has been reported, and payment data remains secure.
Vendor Response and Mitigations
Gardyn has released patches via mobile app updates and firmware fixes. Most users received these automatically, but manual checks are recommended. The company attributes the vulnerabilities to prior unpatched issues highlighted by researcher Kristof Mattei in 2025.
Why This Matters for ICS/OT Security
These flaws underscore the fragility of IoT ecosystems in industrial and home environments. As ICS/OT systems become more interconnected, even consumer devices like smart gardens can serve as entry points for broader attacks. Proactive patching and credential management are essential to mitigate such risks.
Take Action: Secure Your ICS/OT Devices
- Update all Gardyn devices immediately via the mobile app.
- Change default credentials on IoT devices regularly.
- Monitor network traffic for unusual activity.
- Stay informed about vendor security advisories.
