Executive Summary

This is a Server-Side Request Forgery (SSRF) vulnerability in SAP NetWeaver AS Java (Web Services). An unauthenticated attacker can send a crafted SOAP request to force the server to return a SOAP fault to a URL controlled by the attacker. This allows disclosure of information about connected systems, affecting confidentiality only.

Detection Guidance

Detecting SSRF vulnerabilities like CVE-2026-89129 typically involves monitoring network traffic for unusual outbound requests from SAP NetWeaver AS Java servers. Check logs for SOAP faults or unexpected connections to external URLs. Use network scanners to identify SAP NetWeaver instances and inspect their configurations for exposed SOAP endpoints.

Impact Analysis

An attacker could exploit this to gain access to sensitive information about your connected systems, such as internal network details or system configurations. This could lead to further attacks or data breaches if additional vulnerabilities are present.

Compliance Impact

This vulnerability could lead to unauthorized disclosure of personal or sensitive data, violating GDPR and HIPAA requirements for data confidentiality and protection. Organizations may face compliance penalties if exploited.

Mitigation Strategies

Apply the latest SAP security patches from SAP Note 3835738. Restrict outbound network access from SAP NetWeaver servers to trusted domains only. Disable unnecessary SOAP endpoints and implement strict input validation for SOAP requests. Monitor for suspicious outbound connections or SOAP faults.
