"Due to missing authorization check, SAP NetWeaver Application Server for ABAP allows an authenticated attacker to
access content on the start screen of any transaction that is available with in the same SAP system even if he/she isn't
authorized for that transaction. A successful exploitation could expose information and in worst case manipulate data 
before the start screen is executed, resulting in limited impact on confidentiality and integrity of the application.

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