Not applicable - requires code modification
Web Application Firewall
allDeploy WAF with SQL injection rules to block malicious requests
Not applicable - configuration dependent
🧯 If You Can't Patch
- Isolate the CADClick application behind a reverse proxy with strict input validation
- Implement network segmentation to limit database access from the application server
🔍 How to Verify
Check if Vulnerable:
Test ccHandler.aspx with SQL injection payloads in bomid parameter (e.g., ccHandler.aspx?bomid=1' OR '1'='1)Check Version:
Check CADClick version in application interface or configuration filesVerify Fix Applied:
Verify parameterized queries or input validation is implemented in ccHandler.aspx code📡 Detection & Monitoring
Log Indicators:
- Unusual SQL error messages in application logs
- Multiple requests to ccHandler.aspx with suspicious bomid values
Network Indicators:
- HTTP requests containing SQL keywords in bomid parameter
- Unusual database query patterns from application server
SIEM Query:
web.url="*ccHandler.aspx*" AND (web.param="*bomid=*'*" OR web.param="*bomid=*%27*")
