Sources and claim methodology

  • Source referenceurl.sap
Upstream source description

Due to a missing authorization check in SAP NetWeaver Application Server for ABAP, an authenticated attacker with user privileges could read Database Analyzer Log Files via a specific RFC function module. The attacker with the necessary privileges to execute this function module could potentially escalate their privileges and read the sensitive data, resulting in a limited impact on the confidentiality of the information stored. However, the integrity and availability of the system are not affected.
