J2EE Misconfiguration: Unsafe Bean Declaration

Java/JSP

Abstract

不应将实体 bean 声明为远程。

Explanation

当实体 bean 公开远程接口时，会扩大应用程序的攻击面。出于性能原因，应用程序应该很少使用远程实体 bean，因此远程实体 bean 声明很可能是一个错误。

示例 1：以下实体 bean 声明包括一个远程接口：


<ejb-jar>
<enterprise-beans>
<entity>
<ejb-name>EmployeeRecord</ejb-name>
<home>com.wombat.empl.EmployeeRecordHome</home>
<remote>com.wombat.empl.EmployeeRecord</remote>
...
</entity>
...
</enterprise-beans>
</ejb-jar>
