Summary
SAP NetWeaver Application Server ABAP and ABAP Platform allows an authenticated attacker with normal privileges to obtain a valid signed message and send modified signed XML documents to the verifier. This may result in acceptance of tampered identity information leading to unauthorized access to sensitive user data and potential disruption of normal system usage. This causes a high impact on confidentiality, integrity and availability of the application.
