SAP NetWeaver Application Server for ABAP and ABAP Platform: integer underflow
No fix yet
SAP NetWeaver Application Server for ABAP and ABAP Platform allows an unauthenticated user to send a specially crafted packet that triggers reprocessing of a previously buffered user request, potentially hijacking another user's session under narrow timing conditions. Successful exploitation could result in high impact on confidentiality and integrity, with low impact on availability of the application.
