CWE-8 J2EE误配置：实体Bean远程声明
J2EE Misconfiguration: Entity Bean Declared Remote
结构: Simple
Abstraction: Variant
状态: Incomplete
被利用可能性: unkown
基本描述
When an application exposes a remote interface for an entity bean, it might also expose methods that get or set the bean's data. These methods could be leveraged to read sensitive information, or to change data in ways that violate the application's expectations, potentially leading to other vulnerabilities.

可能的缓解方案
Implementation
策略:
Declare Java beans "local" when possible. When a bean must be remotely accessible, make sure that sensitive information is not exposed, and ensure that the application logic performs appropriate validation of any data that might be modified by an attacker.
