Hard-coded Administrative Credentials Exposure in Gardyn IoT Hub

IdentifiersCVE-2025-1242CWE-798· Use of Hard-coded Credentials

CVE-2025-1242 is a credential exposure vulnerability affecting the Gardyn ecosystem in which administrative credentials can be extracted from application API responses, through reverse engineering of the Gardyn mobile application, and through reverse engineering of device firmware. The issue effectively exposes embedded or otherwise recoverable administrative credentials used by the Gardyn IoT Hub. According to the provided advisory context, successful extraction of these credentials can allow an unauthenticated remote attacker to obtain full administrative access to the Gardyn IoT Hub and then control connected devices. The associated weakness classification is CWE-798.

ANALYST BRIEF

Impact, mitigation & remediation

What it means. What to do now. Patch path, mitigations, and the assume-compromise checklist.

Impact

What an attacker gets, and what they’ve been doing with it.

Successful exploitation can give an attacker full administrative access to the Gardyn IoT Hub. With that level of access, the attacker can maliciously control connected devices and compromise the confidentiality and integrity of the affected environment. The provided CVSS context indicates high confidentiality and high integrity impact, with no stated availability impact.

Mitigation

If you can’t patch tonight, do this now.

Until remediation is fully deployed, minimize exposure of Gardyn control systems to untrusted networks. CISA-referenced mitigations in the provided context include ensuring devices are not directly accessible from the public internet, placing control system networks and remote devices behind firewalls, and using secure, fully updated VPNs when remote access is required. Additional prudent mitigation for this specific issue is to monitor for unauthorized administrative access and rotate administrative credentials if possible.

Remediation

Patch, then assume compromise.

Apply the vendor-provided fixes referenced in the Gardyn security advisory and CISA advisory ICSA-26-055-03. The provided context indicates affected software includes Gardyn Mobile Application versions before 2.11.0 and Gardyn Cloud API versions prior to 2.12.2026; organizations should upgrade to fixed versions identified by Gardyn and update affected firmware/software across the Gardyn environment. Because the issue involves exposed administrative credentials, remediation should also include rotating or replacing any embedded, default, or recoverable administrative credentials where supported by the vendor.
