CWE-580: clone() Method Without super.clone()
CWE版本: 4.18
更新日期: 2025-09-09
弱点描述
The product contains a clone() method that does not call super.clone() to obtain the new object.
扩展描述
All implementations of clone() should obtain the new object by calling super.clone(). If a class does not follow this convention, a subclass's clone() method will return an object of the wrong type.
常见后果
影响范围: Integrity Other
技术影响: Unexpected State Quality Degradation
潜在缓解措施
阶段: Implementation
描述: Call super.clone() within your clone() method, when obtaining a new object.
阶段: Implementation
描述: In some cases, you can eliminate the clone method altogether and use copy constructors.
检测方法
方法: 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.)
