CVE-2026-24320
📋 TL;DR
This vulnerability in SAP NetWeaver and ABAP Platform allows authenticated attackers to exploit memory management errors by sending specially crafted input with unique characters. This could lead to memory corruption and potential leakage of memory content, affecting systems running vulnerable SAP components. Only authenticated users can exploit this issue.
💻 Affected Systems
- SAP NetWeaver
- SAP ABAP Platform (Application Server ABAP)
📦 What is this software?
⚠️ Risk & Real-World Impact
Worst Case
Memory content leakage revealing sensitive application data or system information to authenticated attackers.
Likely Case
Limited memory content disclosure with minimal impact due to authentication requirement and low CVSS score.
If Mitigated
No impact with proper patching and standard authentication controls in place.
🎯 Exploit Status
Requires authenticated access and specific knowledge of memory management flaws in SAP components
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: Check SAP Note 3678313 for specific patch versions
Vendor Advisory: https://me.sap.com/notes/3678313
Restart Required: Yes
Instructions:
1. Review SAP Note 3678313 for specific patch details
2. Apply SAP Security Patch Day updates
3. Restart affected SAP services after patching
4. Verify patch application through system checks
🔧 Temporary Workarounds
Restrict authenticated user access
allLimit access to SAP systems to only necessary authenticated users
Input validation enhancement
allImplement additional input validation for SAP applications to filter unusual character sequences
🧯 If You Can't Patch
- Implement strict access controls to limit authenticated user access to minimum necessary
- Monitor SAP application logs for unusual input patterns or memory-related errors
🔍 How to Verify
Check if Vulnerable:
Check SAP system version against affected versions listed in SAP Note 3678313Check Version:
Use SAP transaction code SM51 or system administration tools to check versionVerify Fix Applied:
