CVE-2025-0053
📋 TL;DR
SAP NetWeaver Application Server for ABAP and ABAP Platform contains an information disclosure vulnerability where unauthenticated attackers can access system configuration details via a specific URL parameter. This affects organizations running vulnerable SAP ABAP systems, potentially exposing sensitive configuration data that could aid further attacks.
💻 Affected Systems
- SAP NetWeaver Application Server for ABAP
- SAP ABAP Platform
📦 What is this software?
⚠️ Risk & Real-World Impact
Worst Case
Attackers obtain detailed system configuration information that could be used to plan targeted attacks, identify other vulnerabilities, or facilitate lateral movement within the SAP environment.
Likely Case
Attackers gather reconnaissance data about SAP system configuration, version information, and potentially sensitive configuration details that could inform subsequent attacks.
If Mitigated
Limited information disclosure with minimal impact if proper network segmentation and access controls prevent external access to vulnerable endpoints.
🎯 Exploit Status
Exploitation requires only specific URL parameter manipulation; no authentication required.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: Check SAP Note 3536461 for specific patch versions
Vendor Advisory: https://me.sap.com/notes/3536461
Restart Required: Yes
Instructions:
1. Review SAP Note 3536461 for affected versions and patches. 2. Apply the relevant SAP Security Note via SAP Support Portal. 3. Restart affected SAP instances. 4. Verify patch application via transaction SNOTE.
🔧 Temporary Workarounds
Network Access Control
allRestrict network access to SAP NetWeaver systems to trusted IP addresses only
Web Dispatcher Filtering
allConfigure SAP Web Dispatcher to filter or block requests containing the vulnerable URL parameter
🧯 If You Can't Patch
- Implement strict network segmentation to isolate SAP systems from untrusted networks
- Deploy web application firewall (WAF) rules to block requests with the vulnerable parameter pattern
🔍 How to Verify
Check if Vulnerable:
Test by attempting to access the vulnerable URL parameter on SAP NetWeaver systems; specific parameter details are in SAP Note 3536461
Check Version:
Execute transaction SM51 or SM50 to check SAP kernel and system version
Verify Fix Applied:
Check transaction SNOTE to verify SAP Note 3536461 is applied, then retest vulnerable URL parameter access
