- Weakness Name
Serializable Class Containing Sensitive Data
- Description
The code contains a class with sensitive data, but the class does not explicitly deny serialization. The data can be accessed by serializing the class through another class.
Serializable classes are effectively open classes since data cannot be hidden in them. Classes that do not explicitly deny serialization can be serialized by any other class, which can then in turn use the data stored inside it.
- Common Consequences
Scope: Confidentiality
Impact: Read Application Data
Notes: an attacker can write out the class to a byte stream, then extract the important data from it.
