CVE-2020-9306Public exploit

Remote device access via hard-coded Python credentials

Published Feb 17, 2021 · Updated Aug 4, 2024

Hard-coded credentials in Tesla SolarCity Solar Monitoring Gateway 5.46.43 and earlier allow remote attackers to access the device. The firmware's password_manager.pyc embeds five plaintext passwords for the Python account and selects one by firmware version and connectivity state. Local-network access is required; a matching shared password grants non-administrative SSH or web access for data extraction, persistence, or service interruption.
