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.
