DescriptionSAP Gateway activates the default Access Control List with high privileges allowing categorization of external attacker as internal application server. As a result an unauthenticated attacker with network access to the SAP Gateway could exploit this weakness to potentially perform unauthorized actions within the application environment, resulting in a high impact on the confidentiality, integrity, and availability of the affected system.
