Description
The program 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.
Modes of Introduction:
– Implementation
Likelihood of Exploit: High
Related Weaknesses
Consequences
Integrity, Confidentiality, Availability: Execute Unauthorized Code or Commands
If a program relies solely on the name of an object to determine identity, it may execute the incorrect or unintended code.
Potential Mitigations
Phase: Implementation
Description:
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.
