|---|---|---|
| Integrity Other | Unexpected State, Quality Degradation 注意： If a class does not follow this convention, a subclass's clone() method will return an object of the wrong type. |
潜在缓解措施
Phases : ImplementationAll implementations of clone() should obtain the new object by calling super.clone().
Phases : Implementation
In some cases, you can eliminate the clone method altogether and use copy constructors.

Automated Static Analysis
Automated static analysis, commonly referred to as Static Application Security Testing (SAST), can find some instances of this weakness by analyzing source code (or binary/compiled code) without having to execute it. Typically, this is done by building a model of data flow and control flow, then searching for potentially-vulnerable patterns that connect "sources" (origins of input) with "sinks" (destinations where the data interacts with external components, a lower layer such as the OS, etc.)有效性 : High
漏洞映射说明
依据 : This CWE entry is at the Variant 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.
