[ESNC-2039348] Multiple Critical Security Vulnerabilities in SAP
Governance, Risk and Compliance (SAP GRC)

Please refer to http://www.esnc.de for the original security advisory,
updates and additional information.

1. Business Impact

According to SAP, "SAP Governance, Risk, and Compliance solutions (SAP
GRC solutions) offer your organization a preventive, real-time
approach to governance, risk, and compliance. Automated risk and
compliance monitoring activities can help you proactively prevent risk
events and compliance violations, helping you protect the value of
your organization"

SAP GRC Access Control has multiple remote vulnerabilities, which may
allow an attacker to elevate privileges, bypass SoD restrictions and
execute arbitrary programs. An attacker can also exploit these
vulnerabilities remotely using RFC protocol or if SOAP-RFC is active,
through http/https.

Due to the nature of the business functionality SAP GRC modules offer,
we believe the issue is rather critical.

Risk Level: High
