CWE-9: 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 product.
How it's found
J2EE Misconfiguration: Weak Access Permissions for EJB Methods is a specific, narrowly defined instance of a broader pattern. Testers confirm it with targeted code review and a proof-of-concept input that exercises the exact code path this weakness describes.
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.
Consequences
- Other
Mitigations
- Architecture and Design/System Configuration: Follow the principle of least privilege when assigning access rights to EJB methods. Permission to invoke EJB methods should not be granted to the ANYONE role.
