J2EE Misconfiguration: Weak Access Permissions for EJB Methods

Opis

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

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.
