CWE-1326 Details

A missing immutable root of trust in the hardware results in the ability to bypass secure boot or execute untrusted or adversarial boot code.

Einführungsmodi

Architecture and Design
Implementation : Such issues could be introduced during policy definition, hardware architecture, design, manufacturing, and/or provisioning. They can be identified later during testing or system configuration phases.

Häufige Konsequenzen

Mögliche Gegenmaßnahmen

Phases : Architecture and Design
When architecting the system, the RoT should be designated for storage in a memory that does not allow further programming/writes.
Phases : Implementation
During implementation and test, the RoT memory location should be demonstrated to not allow further programming/writes.

Erkennungsmethoden

Automated Dynamic Analysis

Automated testing can verify that RoT components are immutable.
Wirksamkeit : High

Architecture or Design Review

Root of trust elements and memory should be part of architecture and design reviews.
Wirksamkeit : High

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.
