Common Consequences
Scope Impact Likelihood
Access Control Bypass Protection Mechanism
An untrusted component can master transactions on the
HW bus and target memory or other assets to compromise
the SoC boot firmware.

Potential Mitigations
Phase: Architecture and Design
The boot sequence should enable fabric access controls and memory protections before
enabling third-party hardware IPs and peripheral microcontrollers that use untrusted firmware.

CWE-1204: Generation of Weak Initialization Vector (IV)
Weakness ID : 1204
Structure : Simple
Abstraction : Base
Description
The product uses a cryptographic primitive that uses an Initialization Vector (IV), but the product
does not generate IVs that are sufficiently unpredictable or unique according to the expected
cryptographic requirements for that primitive.
Extended Description
By design, some cryptographic primitives (such as block ciphers) require that IVs must have certain
properties for the uniqueness and/or unpredictability of an IV. Primitives may vary in how important
these properties are. If these properties are not maintained, e.g. by a bug in the code, then the
cryptography may be weakened or broken by attacking the IVs themselves.
