CVE-2025-42950
📋 TL;DR
CVE-2025-42950 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.

⚠️ Risk & Real-World Impact
Worst Case
Full system compromise allowing attackers to steal sensitive data, modify business-critical information, disrupt operations, and establish persistent access across the SAP landscape.
Likely Case
Privilege escalation leading to unauthorized access to sensitive business data, 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 in place, though the vulnerability still presents significant risk.
🎯 Exploit Status
Exploitation requires user credentials but the vulnerability itself is straightforward to exploit once access is obtained
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: See SAP Note 3633838 for specific patch information
Vendor Advisory: https://me.sap.com/notes/3633838
Restart Required: Yes
Instructions:
1. Review SAP Note 3633838 for your specific SLT version. 2. Apply the security patch from SAP. 3. Restart the affected SAP systems. 4. Verify the patch is correctly applied.
🔧 Temporary Workarounds
Restrict RFC Access
allLimit access to RFC function modules to only trusted systems and users
Use SAP transaction SM59 to review and restrict RFC destinations
Use transaction SMT1 to manage trusted RFC connections
Implement Authorization Controls
allStrengthen authorization checks and implement additional security controls
Review and tighten authorization objects in transaction SU24
Implement additional security checks in custom code
🧯 If You Can't Patch
- Implement strict network segmentation to isolate SAP SLT systems from untrusted networks
- Enforce least privilege access controls and regularly audit user permissions
🔍 How to Verify
Check if Vulnerable:
Check if your SAP SLT version matches those listed in SAP Note 3633838 and verify if the security patch has been appliedCheck Version:
Use SAP transaction SM51 or run report RSABAP_SOURCE_SCAN to check system detailsVerify Fix Applied:
Verify the patch is applied by checking system status and confirming the fix version from SAP Note 3633838📡 Detection & Monitoring
Log Indicators:
- Unusual RFC calls to SLT function modules
- Authorization failures followed by successful executions
- ABAP code execution patterns in security audit logs
Network Indicators:
- Unusual RFC traffic patterns to SLT systems
- Suspicious connections to RFC ports (typically 33xx)
