Executive Summary
A CVSS 10.0 Critical server-side request forgery (SSRF) vulnerability has been disclosed in SAP Data Quality Management, tracked as CVE-2026-57106. The flaw allows an unauthenticated remote attacker to perform privilege escalation over the network by abusing the SSRF condition to interact with internal services and components without authorization.
CVSS Score: 10.0 (Critical)
SSRF vulnerabilities at this severity level are particularly dangerous in enterprise SAP environments because they can be chained to reach internal SAP services, cloud metadata endpoints, and backend systems that are otherwise network-isolated, effectively bypassing perimeter controls entirely.

Understanding the Attack
What is SSRF?
Server-Side Request Forgery (SSRF) occurs when an attacker can cause the server to make HTTP requests to attacker-controlled or internal destinations. In enterprise environments, this frequently allows:
- Access to cloud metadata services (e.g.,
169.254.169.254on AWS/Azure/GCP) - Interaction with internal APIs not intended to be publicly accessible
- Bypassing network segmentation and firewall rules
- Credential theft from cloud instance metadata endpoints
CVE-2026-57106 Attack Chain
1. Attacker sends crafted unauthenticated HTTP request to SAP Data Quality endpoint
2. Application processes attacker-supplied URL without proper validation
3. SAP server issues request to internal destination on attacker's behalf
4. Attacker receives response from internal service via the SSRF reflection
5. Internal service credentials, tokens, or session data may be exfiltrated
6. Attacker leverages acquired credentials to escalate privileges within SAP environmentImpact of Successful Exploitation
| Impact | Description |
|---|---|
| Privilege Escalation | Gain elevated access within SAP without authentication |
| Internal Network Access | Reach SAP backend services, databases, and APIs |
| Cloud Metadata Theft | Steal cloud IAM credentials from metadata endpoints |
| Credential Exfiltration | Harvest SAP service account tokens and keys |
| Lateral Movement | Pivot to connected SAP and non-SAP systems |
| Data Exfiltration | Access sensitive data quality and master data records |
Immediate Remediation
Step 1: Apply SAP Security Note
Log in to the SAP Support Portal and apply the relevant SAP Security Note for CVE-2026-57106. Check SAP Security Patch Day notes for July 2026.
# Verify current SAP Data Quality Management patch level
# Navigate to: SAP Support → Systems → Software Information
# Apply the SAP Security Note via SNOTE transaction in SAP GUI
# Transaction: SNOTE → Search by Note number → ImplementStep 2: Restrict SAP Data Quality Network Exposure
1. Place SAP Data Quality Management behind a Web Application Firewall (WAF)
2. Block outbound requests from SAP application servers to:
- Cloud metadata IPs: 169.254.169.254
- Internal subnet ranges not required by the application
3. Implement SAP Network and Transport Layer Security (NLS) policies
4. Use SAP Secure Network Communications (SNC) where possible
Step 3: Enable SAP Threat Detection
1. Enable SAP Security Audit Log (transaction SM19/SM20)
2. Forward SAP logs to SIEM for anomaly detection
3. Configure alerts for unexpected outbound HTTP requests from SAP systems
4. Enable SAP Enterprise Threat Detection (ETD) if licensed
If Immediate Patching Is Not Possible
- Block external access to SAP Data Quality Management endpoints via firewall rules
- Restrict outbound HTTP/HTTPS from SAP application servers to known-good destinations only
- Enable URL allowlisting within SAP to prevent arbitrary outbound requests
- Monitor SAP audit logs (SM20) for unusual request patterns
- Isolate the affected system from internet-facing networks
Detection Indicators
| Indicator | Description |
|---|---|
| Outbound requests to 169.254.169.254 | SSRF attempt targeting cloud metadata service |
| Unexpected HTTP calls to internal RFC ports | SSRF pivoting to SAP internal services |
| Unauthenticated requests to Data Quality endpoints | Pre-auth exploitation attempts |
| Anomalous SAP privilege changes | Post-exploitation privilege escalation activity |
| New RFC connections or background jobs | Post-compromise persistence mechanisms |
SSRF Prevention in SAP Environments
Beyond patching, implement defense-in-depth:
Network Controls:
├── Egress filtering from SAP application servers
├── Block metadata service IPs at perimeter firewall
├── Microsegment SAP systems from general corporate network
└── Deploy WAF with SSRF rule sets in front of SAP web services
Application Controls:
├── SAP URL allowlisting for outbound HTTP clients
├── SNC encryption for inter-SAP communications
├── Disable unused SAP web services and ICM endpoints
└── Regular SAP vulnerability scans via SAP Solution Manager
Monitoring:
├── SAP Security Audit Log (SM19/SM20) — enable and review
├── SIEM integration for SAP log forwarding
├── Alerting on outbound HTTP to RFC/internal port ranges
└── SAP Enterprise Threat Detection (if available)
Post-Remediation Steps
- Confirm SAP Security Note has been implemented and system is at patched level
- Review SAP audit logs for evidence of prior exploitation
- Rotate all service account credentials in the affected SAP system
- Audit RFC connections and background job configurations
- Verify egress filtering is blocking unexpected outbound destinations
- Test SSRF mitigations by attempting requests to 169.254.169.254 from SAP context
- Review SAP user privileges for unauthorized escalations
