🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: Unknown
Vendor Advisory: Not available
Restart Required: No
Instructions:
1. Monitor vendor website for security updates
2. Apply patch when available
3. Test in non-production environment first

🔍 How to Verify
Check if Vulnerable:
Test the /cpasList/findArchiveReportByDah endpoint with SQL injection payloads like ' OR '1'='1Check Version:
Check CPAS system version in administration panel or configuration filesVerify Fix Applied:
Verify that SQL injection payloads no longer execute and return appropriate error messages📡 Detection & Monitoring
Log Indicators:
- Unusual SQL error messages in application logs
- Multiple failed login attempts from single IP
- Requests to /cpasList/findArchiveReportByDah with SQL keywords
Network Indicators:
- Unusual database connection patterns
- Large data transfers from database server
SIEM Query:
source="web_logs" AND uri="/cpasList/findArchiveReportByDah" AND (payload="UNION" OR payload="SELECT" OR payload="INSERT" OR payload="DELETE")
