CWE - CWE-1301: Insufficient or Incomplete Data Removal within Hardware Component (4.16)

Weakness ID: 1301

Vulnerability Mapping: ALLOWED This CWE ID may be used to map to real-world vulnerabilities
Abstraction: Base 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.

Description

The product's data removal process does not completely delete all data and potentially sensitive information within hardware components.

Extended Description

Physical properties of hardware devices, such as remanence of magnetic media, residual charge of ROMs/RAMs, or screen burn-in may still retain sensitive data after a data removal process has taken place and power is removed.

Recovering data after erasure or overwriting is possible due to a phenomenon called data remanence. For example, if the same value is written repeatedly to a memory location, the corresponding memory cells can become physically altered to a degree such that even after the original data is erased that data can still be recovered through physical characterization of the memory cells.

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	Technical Impact: Read Memory; Read Application Data

Potential Mitigations

Phase: Architecture and Design

Apply blinding or masking techniques to implementations of cryptographic algorithms.

Phase: Implementation

Alter the method of erasure, add protection of media, or destroy the media to protect the data.

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.

Description

CVE-2019-8575

Firmware Data Deletion Vulnerability in which a base station factory reset might not delete all user information. The impact of this enables a new owner of a used device that has been "factory-default reset" with a vulnerable firmware version can still retrieve, at least, the previous owner's wireless network name, and the previous owner's wireless security (such as WPA2) key. This issue was addressed with improved, data deletion.

Vulnerability Mapping Notes

Usage: ALLOWED

(this CWE ID may 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.

Notes

Maintenance

This entry is still under development and will continue to see updates and content improvements.
