名稱: 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.

| 範圍 | 影響 | 可能性 |
|---|---|---|
| Access Control Integrity | Modify Memory, Execute Unauthorized Code or Commands, Gain Privileges or Assume Identity 注意：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 own code. | High |

CVE-2019-2267 | Locked memory regions may be modified through other interfaces in a secure-boot-loader image due to improper access control. |
潛在緩解措施
Phases : Architecture and DesignEnsure 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.
偵測方法
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.有效性 : High
Manual Analysis
有效性 : Moderate漏洞對應備注
理由說明 : 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.備註 : 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.

| CAPEC ID | 攻擊模式名稱 |
|---|---|
| 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. |
