Nom: Sensitive Non-Volatile Information Not Protected During Debug

Access to security-sensitive information stored in fuses is not limited during debug.

Description du CWE

Several security-sensitive values are programmed into fuses to be used during early-boot flows or later at runtime. Examples of these security-sensitive values include root keys, encryption keys, manufacturing-specific information, chip-manufacturer-specific information, and original-equipment-manufacturer (OEM) data. After the chip is powered on, these values are sensed from fuses and stored in temporary locations such as registers and local memories. These locations are typically access-control protected from untrusted agents capable of accessing them. Even to trusted agents, only read-access is provided. However, these locations are not blocked during debug operations, allowing a user to access this sensitive information.

Notes de cartographie des vulnérabilités

Justification : 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.
Commentaire : 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.

Modèles d'attaque associés

CAPEC-ID Nom du modèle d'attaque
CAPEC-116 Excavation
An adversary actively probes the target in a manner that is designed to solicit information that could be leveraged for malicious purposes.
CAPEC-545 Pull Data from System Resources
An adversary who is authorized or has the ability to search known system resources, does so with the intention of gathering useful information. System resources include files, memory, and other aspects of the target system. In this pattern of attack, the adversary does not necessarily know what they are going to find when they start pulling data. This is different than CAPEC-150 where the adversary knows what they are looking for due to the common location.
