CVE-2018-6011: Rainmachine Mini-8 Firmware

High severity, CVSS 8.1. EPSS: 1.1% chance of exploitation in the next 30 days.

The time-based one-time-password (TOTP) function in the application logic of the Green Electronics RainMachine Mini-8 (2nd generation) uses the administrator's password hash to generate a 6-digit temporary passcode that can be used for remote and local access, aka a "Use of Password Hash Instead of Password for Authentication" issue. This is exploitable by an attacker who discovers a hash value in the rainmachine-settings.sqlite file.

Affected products

• Rainmachine Mini-8 Firmware: from 4.0.539, up to and including 4.0.975
