Nazwa: Missing Write Protection for Parametric Data Values
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.
Informacje ogólne
Sposoby wprowadzenia
Architecture and Design : The lack of a requirement to protect parametric values may contribute to this weakness.Implementation : The lack of parametric value protection may be a cause of this weakness.

Potencjalne środki zaradcze
Phases : Architecture and DesignAccess controls for sensor blocks should ensure that only trusted software is allowed to change threshold limits and sensor parametric data.
Uwagi dotyczące mapowania podatności
Uzasadnienie : This CWE entry is at the Base level of abstraction, which is a preferred level of abstraction for mapping to the root causes of vulnerabilities.Komentarz : Carefully read both the name and description to ensure that this mapping is an appropriate fit. Do not try to 'force' a mapping to a lower-level Base/Variant simply to comply with this preferred level of abstraction.

| CAPEC-1 | Accessing Functionality Not Properly Constrained by ACLs
In applications, particularly web applications, access to functionality is mitigated by an authorization framework. This framework maps Access Control Lists (ACLs) to elements of the application's functionality; particularly URL's for web apps. In the case that the administrator failed to specify an ACL for a particular element, an attacker may be able to access it with impunity. An attacker with the ability to access functionality not properly constrained by ACLs can obtain sensitive information and possibly compromise the entire application. Such an attacker can access resources that must be available only to users at a higher privilege level, can access management sections of the application, or can run queries for data that they otherwise not supposed to. |
