Insufficient or Incomplete Data Removal within Hardware Component

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.

Observed Examples

Reference Description
CVE-2019-8575Firmware 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.

Potential Mitigations

Phases : Architecture and Design
Apply blinding or masking techniques to implementations of cryptographic algorithms.
Phases : Implementation
Alter the method of erasure, add protection of media, or destroy the media to protect the data.

Vulnerability Mapping Notes

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.

Related Attack Patterns

CAPEC-ID Attack Pattern Name
CAPEC-37 Retrieve Embedded Sensitive Data
An attacker examines a target system to find sensitive data that has been embedded within it. This information can reveal confidential contents, such as account numbers or individual keys/credentials that can be used as an intermediate step in a larger attack.

Notes

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