CWE-486

Comparison of Classes by Name

Variant EXPLOIT LIKELIHOOD: HIGH

What it is

The product compares classes by name, which can cause it to use the wrong class when multiple classes can have the same name.

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.

Impact

Integrity, Confidentiality, AvailabilityExecute Unauthorized Code or Commands

Mitigations

  • [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.
