Unauthorized access via unchangeable hard-coded credentials
Published Feb 1, 2024 · Updated Aug 22, 2024
Hard-coded credentials in MachineSense FeverWarn devices allow remote attackers to gain device access over a network. The embedded ESP32, RaspberryPi, and DataHub RaspberryPi credentials cannot be changed by a user or administrator; public records do not identify the credential store or affected service. No prior access or user interaction is required, and exploitation permits user-data theft, remote code execution, or malicious control of the device.
