Executive brief
The admin panel for Gardyn smart gardening systems lacks standard security headers, which are basic protections used by web browsers to prevent malicious interference. This omission makes the system vulnerable to clickjacking and cross-site scripting, where an attacker could trick a user into performing unintended actions or steal sensitive session information. While there is no evidence of active exploitation, these flaws could compromise the privacy of plant data or user account details if a user visits a malicious website while logged into their Gardyn account.
Technical details
The vulnerability is classified as an improper neutralization of HTTP headers (CWE-644) within the Gardyn admin panel. The absence of standard security headers (such as Content-Security-Policy or X-Frame-Options) allows for clickjacking and cross-site scripting (XSS) attacks. An unauthenticated remote attacker can exploit this by inducing a legitimate user to interact with a malicious link or framed page, potentially leading to unauthorized actions or information disclosure. Gardyn has remediated the issue by updating the Cloud API and deploying firmware updates (master.627 or later) which are automatically applied when devices are connected to the internet.
