Modify /administrator/components/menu/index.php to validate menu_filter parameter
WAF Rule Implementation
allDeploy web application firewall rules to block SQL injection patterns in menu_filter parameter.
Add WAF rule: Detect SQL injection patterns in menu_filter parameter
🧯 If You Can't Patch
- Restrict access to /administrator/ directory to trusted IP addresses only
- Implement database user with minimal privileges (read-only where possible)
🔍 How to Verify
Check if Vulnerable:
Test the /administrator/components/menu/ endpoint with SQL injection payloads in menu_filter parameter (e.g., menu_filter=3' OR '1'='1).Check Version:
Check Cuppa CMS version in configuration files or admin interface.Verify Fix Applied:
Verify that SQL injection payloads no longer execute and return appropriate error messages or are blocked.📡 Detection & Monitoring
Log Indicators:
- Unusual SQL queries in database logs
- Multiple failed login attempts followed by menu_filter parameter manipulation
- Error messages containing SQL syntax in web server logs
Network Indicators:
- HTTP requests to /administrator/components/menu/ with suspicious menu_filter parameters
- Unusual database connection patterns from web server
SIEM Query:
source="web_logs" AND uri="/administrator/components/menu/" AND (menu_filter CONTAINS "'" OR menu_filter CONTAINS "OR" OR menu_filter CONTAINS "UNION")
