CWE-486
Comparison of Classes by Name
VariantDraftSimple
The product compares classes by name, which can cause it to use the wrong class when multiple classes can have the same name.
Extended description
If the decision to trust the methods and data of an object is based on the name of a class, it is possible for malicious users to send objects of the same name as trusted classes and thereby gain the trust afforded to known classes and types.
Common consequences1
- IntegrityConfidentialityAvailabilityExecute Unauthorized Code or Commands
If a product relies solely on the name of an object to determine identity, it may execute the incorrect or unintended code.
Potential mitigations1
- Implementation
Use class equivalency to determine type. Rather than use the class name to determine if an object is of a given type, use the getClass() method, and == operator.
