"A directory traversal vulnerability exists in SAP NetWeaver Application Server for ABAP and ABAP Platform - versions 
700, 701, 702, 731, 740, 750, 751, 752, 753, 754, 755, 756, 757, 791, allowing an attacker with non-administrative
authorizations to exploit a directory traversal flaw in an available service to overwrite the system files. In this
attack, no data can be read but potentially critical OS files can be overwritten making the system unavailable.

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version
number.");
