Executive Summary

This vulnerability is due to Broken Access Control in SAP NetWeaver AS Java. An unauthenticated attacker can invoke affected SOAP operations over HTTP without proper access control. This could lead to disclosure of information accessible through the affected service, impacting confidentiality.

Detection Guidance

Detecting this vulnerability requires checking for exposed SOAP services in SAP NetWeaver AS Java. Use network scanning tools like nmap to identify SAP NetWeaver services on port 50000 or 50001. Example command: nmap -p 50000,50001 -sV <target_IP>. Review SAP logs for unauthorized SOAP requests or access attempts.

Impact Analysis

An attacker could exploit this to access sensitive information exposed by the affected service. Since integrity and availability are unaffected, the primary risk is unauthorized data disclosure. The impact is low but could affect confidentiality of data.

Compliance Impact

This vulnerability could potentially affect compliance with GDPR and HIPAA due to the disclosure of information accessible through the affected service. GDPR requires protection of personal data, and HIPAA mandates safeguards for protected health information. A low confidentiality impact could still lead to unauthorized access, posing risks to compliance.

Mitigation Strategies

Apply SAP Security Notes referenced in SAP Note 3792447. Restrict access to SOAP services by configuring proper access controls. Disable unnecessary SOAP operations and ensure SAP NetWeaver AS Java is updated to the latest patch level. Monitor network traffic for suspicious activity targeting SAP services.
