CWE - CWE-1263: Improper Physical Access Control (4.16)

Weakness ID: 1263

Vulnerability Mapping: ALLOWED This CWE ID could be used to map to real-world vulnerabilities in limited situations requiring careful review (with careful review of mapping notes)
Abstraction: Class Class - 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.

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 product is designed with access restricted to certain information, but it does not sufficiently protect against an unauthorized actor with physical access to these areas.

Extended Description

Sections of a product intended to have restricted access may be inadvertently or intentionally rendered accessible when the implemented physical protections are insufficient. The specific requirements around how robust the design of the physical protection mechanism needs to be depends on the type of product being protected. Selecting the correct physical protection mechanism and properly enforcing it through implementation and manufacturing are critical to the overall physical security of the product.

Common Consequences

This 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.

Scope	Impact	Likelihood
Confidentiality Integrity Access Control	Technical Impact: Varies by Context

Potential Mitigations

Phase: Architecture and Design

Specific protection requirements depend strongly on contextual factors including the level of acceptable risk associated with compromise to the product's protection mechanism. Designers could incorporate anti-tampering measures that protect against or detect when the product has been tampered with.

Phase: Testing

The testing phase of the lifecycle should establish a method for determining whether the protection mechanism is sufficient to prevent unauthorized access.

Phase: Manufacturing

Ensure that all protection mechanisms are fully activated at the time of manufacturing and distribution.

Relationships

This 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.

Relevant to the view "Research Concepts" (CWE-1000)

Nature	Type	ID	Name
ChildOf	Pillar - a weakness that is the most abstract type of weakness and represents a theme for all class/base/variant weaknesses related to it. A Pillar is different from a Category as a Pillar is still technically a type of weakness that describes a mistake, while a Category represents a common characteristic used to group related things.	284	Improper Access Control
ParentOf	Base - 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.	1243	Sensitive Non-Volatile Information Not Protected During Debug
PeerOf	Base - 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.	1191	On-Chip Debug and Test Interface With Improper Access Control

MemberOf	Category - a CWE entry that contains a set of other entries that share a common characteristic.	1208	Cross-Cutting Problems

Modes Of Introduction

The 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.

Phase	Note
Architecture and Design	This weakness can arise if design decisions are made that do not align with the intended physical protection of the product
Manufacturing	While the architecture and design phase of the product may have accurately met the intended robustness for product physical protections, this phase may introduce the weakness through errors in physically manufacturing the product.

Applicable Platforms

This 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.
