SAP HANA IU5 SDK Application does not enforce any authentication when it is explicitly configured. It could allow an anonymous user to access functions or information that should be restricted.
Risk Level: Medium
Affected Components Description
SAP HANA Extended Application Services (XS) is an application server, web server and development environment for web applications within the SAP HANA System. SAP HANA XS is fully integrated with the SAP HANA Database. SAP HANA IU5 SDK Application is the User Interface Development Toolkit for HTML5 Applications. It allows users to learn, develop and test web applications in a demo environment.
SAP HANA Extend Application Services (XS) based applications can be set to have ?public? access (i.e., no authentication required). Even though this configuration is changed to ?non public? in SAP HANA IU5 SDK Application, no authentication is needed to access thus still allowing public access.
Additional technical details about this issue are not disclosed at this moment with the purpose of providing enough time to affected customers to patch their systems and protect against the exploitation of the described vulnerability.
