Title: Thrive Smart Home v1.1 SQL Injection Authentication Bypass
Advisory ID: ZSL-2019-5554
Type: Local/Remote
Impact: Exposure of System Information, Exposure of Sensitive Information, Manipulation of Data
Risk: (5/5)
Release Date: 29.12.2019
As smart home technology becomes more affordable and easy to install with services offered by Thrive Smart Homes, there are some great options available to give your home a high-tech makeover. If the convenience of feeding your cat or turning on your air conditioning with a tap on your smartphone isn't enough of a reason to make the investment, consider how conveniently you can protect your home and belongings. From Wi-Fi-equipped smoke detectors to plugs with auto turn-offs, smart homes with their always-on connectivity and notifications systems allow consumers to quickly respond to the unexpected. For instance, if you install a smart water leak and moisture monitoring device, you can set up alerts on your phone for unusual changes in moisture and stop leaks before they cause major flooding or mold. It's a convenient way to proactively protect your home from costly damage, whether it's an overflowing laundry tub, a cracked washer hose, or a leaky water heater.
The application suffers from an SQL Injection vulnerability. Input passed through 'user' POST parameter in checklogin.php is not properly sanitised before being returned to the user or used in SQL queries. This can be exploited to manipulate SQL queries by injecting arbitrary SQL code and bypass the authentication mechanism.
