[ESNC-2013-003] Remote OS Command Execution in SAP BASIS Communication Services Please refer to www.esnc.de for the original security advisory, updates and additional information. ------------------------------------------------------------------------ 1. Business Impact ------------------------------------------------------------------------ This vulnerability allows executing arbitrary operating system commands on the remote SAP system with the rights of the SAP application user. By exploiting this vulnerability, an attacker can take complete control of the SAP application and data remotely via e.g. RFC protocol or over the web via SAP's RFC-SOAP interfaces. Attacker can therefore manipulate/extract business data and control the business logic. Although vendor claims confidentiality, integrity and availability is only partially affected (C:P/I:P/A:P) resulting a CVSS score of 6.0, we believe this does not reflect the actual risk. *Risk Level: High* ------------------------------------------------------------------------ 2.
