RainMachine Mini‑8 may let attacker log in with password hash

CVE-2018-6011 · published 8 years ago
Summary

The RainMachine Mini‑8 controller stores the admin password hash in a file that is later used to create a six‑digit login code. If someone obtains that file, they can generate valid codes and gain remote or local access. Protect the file, update the firmware, and change the administrator password as soon as possible.

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.
