CWE-1192: Improper Identifier for IP Block used in System-On-Chip (SOC)

Weakness ID: 1192
Vulnerability Mapping: ALLOWEDThis CWE ID may be used to map to real-world vulnerabilities
Abstraction: BaseBase - a weakness that is still mostly independent of a resource or technology, but with sufficient details to provide specific methods for detection and prevention. Base level weaknesses typically describe issues in terms of 2 or 3 of the following dimensions: behavior, property, technology, language, and resource.
View customized information:
For users who are interested in more notional aspects of a weakness. Example: educators, technical writers, and project/program managers. For users who are concerned with the practical application and details about the nature of a weakness and how to prevent it from happening. Example: tool developers, security researchers, pen-testers, incident response analysts. For users who are mapping an issue to CWE/CAPEC IDs, i.e., finding the most appropriate CWE for a specific issue (e.g., a CVE record). Example: tool developers, security researchers.

+ Description
The System-on-Chip (SoC) does not have unique, immutable identifiers for each of its components.
+ Extended Description

A System-on-Chip (SoC) comprises several components (IP) with varied trust requirements. It is required that each IP is identified uniquely and should distinguish itself from other entities in the SoC without any ambiguity. The unique secured identity is required for various purposes. Most of the time the identity is used to route a transaction or perform certain actions, including resetting, retrieving a sensitive information, and acting upon or on behalf of something else.

There are several variants of this weakness:

  • A "missing" identifier is when the SoC does not define any mechanism to uniquely identify the IP.
  • An "insufficient" identifier might provide some defenses - for example, against the most common attacks - but it does not protect against everything that is intended.
  • A "misconfigured" mechanism occurs when a mechanism is available but not implemented correctly.
  • An "ignored" identifier occurs when the SoC/IP has not applied any policies or does not act upon the identifier securely.
+ Relationships
Section HelpThis table shows the weaknesses and high level categories that are related to this weakness. These relationships are defined as ChildOf, ParentOf, MemberOf and give insight to similar items that may exist at higher and lower levels of abstraction. In addition, relationships such as PeerOf and CanAlsoBe are defined to show similar weaknesses that the user may want to explore.

NatureTypeIDName
ChildOfClassClass - a weakness that is described in a very abstract fashion, typically independent of any specific language or technology. More specific than a Pillar Weakness, but more general than a Base Weakness. Class level weaknesses typically describe issues in terms of 1 or 2 of the following dimensions: behavior, property, and resource.657Violation of Secure Design Principles

+ Modes Of Introduction
Section HelpThe different Modes of Introduction provide information about how and when this weakness may be introduced. The Phase identifies a point in the life cycle at which introduction may occur, while the Note provides a typical scenario related to introduction during the given phase.

+ Applicable Platforms
Section HelpThis listing shows possible areas for which the given weakness could appear. These may be for specific named Languages, Operating Systems, Architectures, Paradigms, Technologies, or a class of such platforms. The platform is listed along with how frequently the given weakness appears for that instance.

Languages

Class: Not Language-Specific (Undetermined Prevalence)

Technologies

Class: System on Chip (Undetermined Prevalence)

+ Common Consequences
Section HelpThis table specifies different individual consequences associated with the weakness. The Scope identifies the application security area that is violated, while the Impact describes the negative technical impact that arises if an adversary succeeds in exploiting this weakness. The Likelihood provides information about how likely the specific consequence is expected to be seen relative to the other consequences in the list. For example, there may be high likelihood that a weakness will be exploited to achieve a certain impact, but a low likelihood that it will be exploited to achieve a different impact.

Technical Impact: Bypass Protection Mechanism

+ Potential Mitigations

Phase: Architecture and Design

Strategy: Separation of Privilege

Every identity generated in the SoC should be unique and immutable in hardware. The actions that an IP is trusted or not trusted should be clearly defined, implemented, configured, and tested. If the definition is implemented via a policy, then the policy should be immutable or protected with clear authentication and authorization.

+ Memberships
Section HelpThis MemberOf Relationships table shows additional CWE Categories and Views that reference this weakness as a member. This information is often useful in understanding where a weakness fits within the context of external information sources.

+ Vulnerability Mapping Notes

Usage: ALLOWED

(this CWE ID could be used to map to real-world vulnerabilities)

Reason: Acceptable-Use

Rationale:

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.

Comments:

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.
