J2EE Misconfiguration: Weak Access Permissions for EJB Methods
If elevated access rights are assigned to EJB methods, then an attacker can take advantage of the permissions to exploit the software system.
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.
The following examples help to illustrate the nature of this weakness and describe methods or techniques which can be used to mitigate the risk.
Note that the examples here are by no means exhaustive and any given weakness may have many subtle varieties, each of which may require different detection methods or runtime controls.
The following deployment descriptor grants ANYONE permission to invoke the Employee EJB's method named getSalary().
