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, unauthorized access to sensitive user data and potential disruption of normal system usage.

Due to a Missing Authorization Check vulnerability in Application Server ABAP and ABAP Platform, an authenticated attacker could misuse an RFC function to execute form routines (FORMs) in the ABAP system. Successful exploitation could allow the attacker to write or modify data accessible via FORMs and invoke system functionality exposed via FORMs, resulting in a high impact on integrity and availability, while confidentiality remains unaffected.

SAP ABAP Platform Kernel - versions 7.77, 7.81, 7.85, 7.86, does not perform necessary authorization checks for an authenticated business user, resulting in escalation of privileges. That means this business user is able to read and modify data beyond the vulnerable system. However, the attacker can neither significantly reduce the performance of the system nor stop the system.
