Name: Incorrect Register Defaults or Module Parameters
Hardware description language code incorrectly defines register defaults or hardware Intellectual Property (IP) parameters to insecure values.
Allgemeine Informationen
Einführungsmodi
Implementation : Such issues could be introduced during implementation of hardware design, since IP parameters and defaults are defined in HDL code and identified later during Testing or System Configuration phases.Anwendbare Plattformen

| Confidentiality Integrity Availability Access Control | Varies by Context Note: Degradation of system functionality, or loss of access control enforcement can occur. |
Mögliche Gegenmaßnahmen
Phases : Architecture and DesignDuring hardware design, all the system parameters and register defaults must be reviewed to identify security sensitive settings.
Phases : Implementation
The default values of these security sensitive settings need to be defined as part of the design review phase.
Erkennungsmethoden
Automated Analysis
Use automated tools to test that values are configured per design specifications.Hinweise zur Schwachstellen-Zuordnung
Begründung : 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.Kommentar : 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-166 | Force the System to Reset Values
An attacker forces the target into a previous state in order to leverage potential weaknesses in the target dependent upon a prior configuration or state-dependent factors. Even in cases where an attacker may not be able to directly control the configuration of the targeted application, they may be able to reset the configuration to a prior state since many applications implement reset functions. |
