Nom: Cloneable Class Containing Sensitive Information

The code contains a class with sensitive data, but the class is cloneable. The data can then be accessed by cloning the class.

Description du CWE

Cloneable classes are effectively open classes, since data cannot be hidden in them. Classes that do not explicitly deny cloning can be cloned by any other class without running the constructor.

Conséquences courantes

Portée Impact Probabilité
Access ControlBypass Protection Mechanism

Note: A class that can be cloned can be produced without executing the constructor. This is dangerous since the constructor may perform security-related checks. By allowing the object to be cloned, those checks may be bypassed.

Mesures d’atténuation potentielles

Phases : Implementation
If you do make your classes clonable, ensure that your clone method is final and throw super.clone().

Notes de cartographie des vulnérabilités

Justification : 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.
Commentaire : 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.
