常見後果

範圍	影響	可能性
Access Control Integrity	Modify Memory 注意：The muitable data could be altered or deleted by the calling function. If this data was not previously cloned, the class will then be using modified data which may violate assumptions about its internal state.

潛在緩解措施

Phases : Implementation
Declare returned data which should not be altered as constant or immutable.
Phases : Implementation
Clone all mutable data before returning references to it. This is the preferred mitigation. This way, regardless of what changes are made to the data, a valid copy is retained for use by the class.

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.
