Due to insufficient input validation, SAP NetWeaver Application Server allows an attacker with high level privileges to use a remote enabled function to read an otherwise restricted file. On successful exploitation an attacker can access and modify the file contents, which may lead to a complete compromise of the confidentiality of the application.
