PatchTheCVECVE-2018-6011: The time-based one-time-password (TOTP) function in the application logic of the Green Electronics RainMachine
CVE-2018-6011 is a high-severity flaw (CVSS 8.1) affecting mini-8 firmware. Below: why it ranks where it does, which versions are affected, what to do, and the exact commands.
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.
Why this priority
- High severity
- Public exploit reference
- Remotely exploitable, no login, no user action
A fixed release or distro patch exists.
