Name: Assumed-Immutable Data is Stored in Writable Memory

Immutable data, such as a first-stage bootloader, device identifiers, and "write-once" configuration settings are stored in writable memory that can be re-programmed or updated in the field.

General Informations

Modes Of Introduction

Implementation : Keys, code, configuration settings, and other data should be programmed in write-once or read-only memory instead of writable memory.

Applicable Platforms

Language

Class: Not Language-Specific (Undetermined)

Operating Systems

Class: Not OS-Specific (Undetermined)

Architectures

Class: Not Architecture-Specific (Undetermined)

Technologies

Class: Not Technology-Specific (Undetermined)

Common Consequences

IntegrityVaries by Context

Potential Mitigations

Phases : Implementation
All immutable code or data should be programmed into ROM or write-once memory.

Vulnerability Mapping Notes

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.
Comment : 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-458 Flash Memory Attacks
An adversary inserts malicious logic into a product or technology via flashing the on-board memory with a code-base that contains malicious logic. Various attacks exist against the integrity of flash memory, the most direct being rootkits coded into the BIOS or chipset of a device.
CAPEC-679 Exploitation of Improperly Configured or Implemented Memory Protections

Notes

This entry is still under development and will continue to see updates and content improvements.
As of CWE 4.3, CWE-1282 and CWE-1233 are being investigated for potential duplication or overlap.
