CVE-2025-31330
📋 TL;DR
CVE-2025-31330 is a critical code injection vulnerability in SAP Landscape Transformation (SLT) that allows authenticated users to execute arbitrary ABAP code via RFC function modules. This effectively creates a backdoor that bypasses authorization checks, potentially leading to complete system compromise. Organizations running vulnerable SAP SLT systems with user accounts are affected.

- Review the CVE details at NVD
- Check vendor security advisories for your specific version
- Test if the vulnerability is exploitable in your environment
- Consider updating to the latest version as a precaution
⚠️ Risk & Real-World Impact
Worst Case
Full system compromise allowing attackers to steal sensitive data, modify business logic, disrupt operations, and establish persistent access across the SAP landscape.
Likely Case
Privilege escalation leading to unauthorized data access, configuration changes, and potential lateral movement within the SAP environment.
If Mitigated
Limited impact if proper network segmentation, strict user access controls, and monitoring are implemented to detect exploitation attempts.
🎯 Exploit Status
Exploitation requires authenticated user access; ABAP code injection via RFC is well-understood attack vector
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: Refer to SAP Note 3587115 for specific patch information
Vendor Advisory: https://me.sap.com/notes/3587115
Restart Required: Yes
Instructions:
1. Review SAP Note 3587115 for your specific SAP SLT version
2. Apply the security patch from SAP Support Portal
3. Restart affected SAP SLT systems
4. Verify patch application via transaction SNOTE
🔧 Temporary Workarounds
Restrict RFC Access
allLimit access to vulnerable RFC function modules using SAP authorization objects and network controls
Use transaction SM59 to review RFC destinations
Implement S_RFC authorization checks
Configure firewall rules to restrict RFC traffic
User Access Review
allReview and restrict user privileges to SAP SLT systems, especially RFC access permissions
Use transaction SUIM to analyze user authorizations
Review PFCG roles for RFC-related permissions
Implement least privilege principle
🧯 If You Can't Patch
- Implement strict network segmentation to isolate SAP SLT systems from untrusted networks
- Enable comprehensive logging and monitoring of RFC function module calls and ABAP code execution
🔍 How to Verify
Check if Vulnerable:
Check if your SAP SLT version is listed as vulnerable in SAP Note 3587115 using transaction SNOTECheck Version:
Execute transaction SM51 or check system information in SAP GUIVerify Fix Applied:
Verify patch application in transaction SPAM/SAINT and confirm no security notes are missing in SNOTE📡 Detection & Monitoring
Log Indicators:
- Unusual RFC function module calls
- ABAP code execution patterns in SLT logs
- Authorization failures for RFC access
Network Indicators:
- Unexpected RFC traffic to SAP SLT systems
- ABAP code patterns in network payloads
