CWE-580: clone() Method Without super.clone()
The product contains a clone() method that does not call super.clone() to obtain the new object.
How it's found
clone() Method Without super.clone() is a specific, narrowly defined instance of a broader pattern. Testers confirm it with targeted code review and a proof-of-concept input that exercises the exact code path this weakness describes.
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.
Consequences
- Unexpected State, Quality Degradation
Mitigations
- Implementation: Call super.clone() within your clone() method, when obtaining a new object.
- Implementation: In some cases, you can eliminate the clone method altogether and use copy constructors.
