CVE-2023-31634Public exploitNetwork attack vector

Unauthenticated Grafana access via preset administrator credentials

Published Mar 27, 2024 · Updated Aug 2, 2024

Improper authentication in TeslaMate before 1.27.2 allows remote attackers to read and modify user data through its web services. The default Docker deployment exposes TeslaMate on port 4000 and configures the Grafana administrator account on port 3000 with preset credentials. Network access to either service is the gate; Grafana access exposes stored vehicle data and permits management-console operations.
