Upstream source description

SAP NetWeaver Application Server for ABAP does not properly validate certain input values. An authenticated user could send specially crafted requests to trigger an error in internal processing. This could crash the affected work process and make the system unavailable. This results in a high impact on availability with no impact on confidentiality and integrity.
