CWE-9 J2EE误配置：EJB方法弱访问权限

J2EE Misconfiguration: Weak Access Permissions for EJB Methods

结构: Simple

Abstraction: Variant

状态: Draft

被利用可能性: unkown

基本描述

If elevated access rights are assigned to EJB methods, then an attacker can take advantage of the permissions to exploit the software system.

扩展描述

If the EJB deployment descriptor contains one or more method permissions that grant access to the special ANYONE role, it indicates that access control for the application has not been fully thought through or that the application is structured in such a way that reasonable access control restrictions are impossible.
