Description
The device does not write-protect the parametric data values for sensors that scale the sensor value, allowing untrusted software to manipulate the apparent result and potentially damage hardware or cause operational failure.
Modes of Introduction:
– Architecture and Design
Related Weaknesses
Consequences
Availability: Quality Degradation, DoS: Resource Consumption (Other)
Sensor value manipulation, particularly thermal or power, may allow physical damage to occur or disabling of the device by a false fault shutdown causing a Denial-Of-Service.
Potential Mitigations
Phase: Architecture and Design
Effectiveness: High
Description:
Access controls for sensor blocks should ensure that only trusted software is allowed to change threshold limits and sensor parametric data.
