名前: CPU Hardware Not Configured to Support Exclusivity of Write and Execute Operations
The CPU is not configured to provide hardware support for exclusivity of write and execute operations on memory. This allows an attacker to execute data from all of memory.
一般情報
背景の詳細
導入モード
Architecture and Design : If the CPU does not have an MMU/MPU, then there is no write exclusivity.適用可能なプラットフォーム

一般的な結果
| スコープ | 影響 | 可能性 |
|---|---|---|
| Confidentiality Integrity | Execute Unauthorized Code or Commands 注記：Without configuring exclusivity of operations via segregated areas of memory, an attacker may be able to inject malicious code onto memory and later execute it. |

脆弱性マッピングノート
理由 : 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.コメント : 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.
