SAP NetWeaver Application Server ABAP and ABAP Platform allows an authenticated, low-privileged user to perform background Remote Function Calls without the required SRFC authorization in certain cases. This can result in a high impact on integrity and availability, and no impact on the confidentiality of the application.

Depending on the configuration of the route permission table in file 'saprouttab', it is possible for an unauthenticated attacker to execute SAProuter administration commands in SAP NetWeaver and ABAP Platform - versions KERNEL 7.49, 7.77, 7.81, 7.85, 7.86, 7.87, 7.88, KRNL64NUC 7.49, KRNL64UC 7.49, SAPROUTER 7.53, 7.22, from a remote client, for example stopping the SAProuter, that could highly impact systems availability.
