Nome: Improper Access Control for Volatile Memory Containing Boot Code

The product conducts a secure-boot process that transfers bootloader code from Non-Volatile Memory (NVM) into Volatile Memory (VM), but it does not have sufficient access control or other protections for the Volatile Memory.

General Informations

Modes Of Introduction

Architecture and Design : This weakness can be introduced during hardware architecture or design but can be identified later during testing.

Conseguenze comuni

Ambito Impatto Probabilità
Access Control
Integrity		Modify Memory, Execute Unauthorized Code or Commands, Gain Privileges or Assume Identity

Note: If the volatile-memory-region protections or access controls are insufficient to prevent modifications from an adversary or untrusted agent, the secure boot may be bypassed or replaced with the execution of an adversary's code.		High

Esempi osservati

Riferimenti Descrizione

CVE-2019-2267

Locked memory regions may be modified through other interfaces in a secure-boot-loader image due to improper access control.

Potential Mitigations

Phases : Architecture and Design
Ensure that the design of volatile-memory protections is enough to prevent modification from an adversary or untrusted code.
Phases : Testing
Test the volatile-memory protections to ensure they are safe from modification or untrusted code.

Detection Methods

Manual Analysis

Ensure the volatile memory is lockable or has locks. Ensure the volatile memory is locked for writes from untrusted agents or adversaries. Try modifying the volatile memory from an untrusted agent, and ensure these writes are dropped.
Effectiveness : High

Manual Analysis

Effectiveness : Moderate

Note sulla mappatura delle vulnerabilità

Giustificazione : 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.
Commento : 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.

Pattern di attacco correlati

CAPEC-ID Nome del pattern di attacco
CAPEC-456 Infected Memory
An adversary inserts malicious logic into memory enabling them to achieve a negative impact. This logic is often hidden from the user of the system and works behind the scenes to achieve negative impacts. This pattern of attack focuses on systems already fielded and used in operation as opposed to systems that are still under development and part of the supply chain.
