A code injection vulnerability exists in SAP NetWeaver Application Server ABAP (Reconciliation Framework). ABAP Server and ABAP Platform may allow a high privileged attacker to inject code that can be executed by the application. An attacker could potentially delete critical information and make the SAP system completely unavailable.
Note that Nessus has not tested for this issue but has instead relied only on the application’s self-reported version number.
