Smart Garage Door Opener Vulnerability Allows Remote Hacking

Security researcher Sam Sabetan has discovered a major security hole in the mobile app for Nexx's smart garage door controller, which allows hackers to remotely open connected doors. The vulnerability is due to a shared universal password that applies across all devices and leaks via Nexx's API and firmware. Sabetan also uncovered four other related vulnerabilities that can involve hijacking Nexx's smart plugs and smart alarm products. Despite attempts to contact the company, Nexx has been silent on fixing the issue. Sabetan estimates that over 40,000 devices are impacted and recommends disconnecting the devices and contacting Nexx for remediation steps.
