名称: 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.
基本信息
背景详情
引入方式
Architecture and Design : If the CPU does not have an MMU/MPU, then there is no write exclusivity.适用平台
编程语言
类： Not Language-Specific (Undetermined)操作系统
类： Not OS-Specific (Undetermined)架构
类： Not Architecture-Specific (Undetermined)技术
名称： Microcontroller Hardware (Undetermined)名称： Processor Hardware (Undetermined)
常见后果
| 影响范围 | 影响 | 可能性 |
|---|---|---|
| Confidentiality Integrity | Execute Unauthorized Code or Commands 注意： 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. |

漏洞映射说明
依据 : 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.备注 : 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.
