CVE-2025-29631
Published: 25 July 2025
Summary
CVE-2025-29631 is a critical-severity OS Command Injection (CWE-78) vulnerability in Mygardyn (inferred from references). Its CVSS base score is 9.8 (Critical).
Operationally, exploitation aligns with the MITRE ATT&CK technique Exploit Public-Facing Application (T1190); ranked in the top 16.0% of CVEs by exploit likelihood; it is not currently listed in the CISA KEV catalog.
The strongest mitigations our analysis identified are NIST 800-53 SI-10 (Information Input Validation) and SI-2 (Flaw Remediation).
Deeper analysis
Gardyn Home Kit firmware before master.619, the associated mobile application before version 2.11.0, and the cloud API before 2.12.2026 contain a command-injection flaw. The affected components fail to sanitize user-supplied input before passing it to operating-system execution routines, enabling arbitrary command execution on the target device. The issue is tracked under CWE-78 and CWE-94 and carries a CVSS 3.1 base score of 9.8.
An unauthenticated attacker with network access can supply crafted input through the vulnerable methods and obtain arbitrary operating-system command execution on an internet-exposed Home Kit. Successful exploitation grants full control over the device, including the ability to read or modify data and potentially pivot to other systems on the same network.
Vendor and government sources direct users to apply the referenced firmware, application, and API updates. The Gardyn security bulletin and the CISA advisory ICSA-26-055-03 provide the official remediation guidance and timelines. The EPSS score has remained flat at 0.02 with no material increase since disclosure.

Why these techniques?
Command injection (CWE-78) in exposed firmware/API enables remote unauthenticated RCE via T1190; arbitrary OS command execution maps to Unix Shell (T1059.004) on embedded device.

Directly addresses the lack of input sanitization by requiring validation of all inputs before passing to the OS, preventing command injection in the firmware, app, and API.
Mandates timely remediation of known flaws like this CVE through patching to the specified firmware master.619+, app 2.11.0+, and API 2.12.2026+ versions.
Restricts input types, amounts, and characteristics to block malicious payloads from reaching vulnerable methods that execute OS commands.
