"Due to a missing authorization check in SAP NetWeaver Application Server for ABAP, an authenticated attacker with basic
privileges could execute a specific function module in ABAP to retrieve restricted technical information from the system.
This disclosure of environment details of the system could further assist this attacker to plan subsequent attacks. As a result, this vulnerability has a low impact on confidentiality, with no impact on the integrity or availability 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.");
