CVE-2023-2809
📋 TL;DR
This vulnerability allows remote attackers to extract plaintext SQL database credentials from Sage 200 Spain's DLL application. Exploitation could lead to remote SQL command execution and privilege escalation on Windows systems. Organizations using Sage 200 Spain 2023.38.001 are affected.
💻 Affected Systems
- Sage 200 Spain
📦 What is this software?
⚠️ Risk & Real-World Impact
Worst Case
Full compromise of SQL database leading to data theft, ransomware deployment, and complete system takeover through privilege escalation.
Likely Case
Database credential theft enabling unauthorized data access, data manipulation, and lateral movement within the network.
If Mitigated
Limited to credential exposure without successful exploitation due to network segmentation and access controls.
🎯 Exploit Status
Credential extraction from DLL is straightforward. Subsequent SQL exploitation requires standard SQL attack techniques.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: Later than 2023.38.001 (check vendor for specific version)
Vendor Advisory: https://www.incibe.es/en/incibe-cert/notices/aviso/use-cleartext-credentials-sage-200
Restart Required: Yes
Instructions:
1. Contact Sage Spain for updated version. 2. Backup data and configurations. 3. Install the patched version. 4. Restart affected systems. 5. Verify credential storage is encrypted.
🔧 Temporary Workarounds
Restrict DLL Access
windowsApply strict file permissions to prevent unauthorized access to the vulnerable DLL.
icacls "C:\Path\To\Sage\Vulnerable.dll" /deny Everyone:(R)
Network Segmentation
allIsolate Sage 200 systems from critical databases and limit SQL server access.
🧯 If You Can't Patch
- Implement strict network segmentation to isolate Sage 200 systems from SQL servers.
- Rotate all SQL database credentials and monitor for unauthorized access attempts.
🔍 How to Verify
Check if Vulnerable:
Check Sage 200 Spain version in application settings or About dialog. If version is 2023.38.001, system is vulnerable.Check Version:
Check application GUI or registry: HKEY_LOCAL_MACHINE\SOFTWARE\Sage\Sage200Spain\VersionVerify Fix Applied:
Verify installed version is newer than 2023.38.001 and check that credentials are no longer stored in plaintext in DLL files.📡 Detection & Monitoring
