💻 Affected Systems
- NUS-M9 ERP Management Software
📦 What is this software?
⚠️ Risk & Real-World Impact
Worst Case
Complete database compromise leading to data theft, authentication bypass, privilege escalation, and potential remote code execution on the database server.
Likely Case
Authentication bypass allowing unauthorized access to the ERP system, followed by data exfiltration and potential lateral movement within the network.
If Mitigated
Limited impact with proper input validation, parameterized queries, and network segmentation preventing database access.
🎯 Exploit Status
Exploitation requires no authentication and simple SQL injection techniques can be used.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: Unknown
Vendor Advisory: Not available
Restart Required: No
Instructions:
No official patch available. Consider implementing workarounds or migrating to alternative software.
🔧 Temporary Workarounds
Web Application Firewall (WAF)
allDeploy a WAF with SQL injection protection rules to block malicious requests.
Input Validation Filter
allImplement server-side input validation to reject suspicious characters in the usercode parameter.
🧯 If You Can't Patch
- Isolate the ERP system behind a firewall with strict access controls
- Implement network segmentation to limit database server exposure
🔍 How to Verify
Check if Vulnerable:
Test the /UserWH/checkLogin endpoint with SQL injection payloads in the usercode parameterCheck Version:
Check software version in application interface or configuration filesVerify Fix Applied:
Verify that SQL injection attempts are blocked or properly sanitized📡 Detection & Monitoring
Log Indicators:
- Unusual SQL error messages in application logs
- Multiple failed login attempts with SQL-like patterns
Network Indicators:
- HTTP requests to /UserWH/checkLogin containing SQL keywords in parameters
SIEM Query:
source="web_logs" AND uri="/UserWH/checkLogin" AND (param="usercode" AND value CONTAINS "' OR '1'='1" OR value CONTAINS "UNION SELECT" OR value CONTAINS "--")
