🔍 How to Verify
Check if Vulnerable:
Test admin/index.php?mode=user&action=edit&userid=1' OR '1'='1 to see if SQL error occursCheck Version:
Check bloofox version in admin panel or configuration filesVerify Fix Applied:
Test same payload after fix - should return proper error or no data instead of SQL error📡 Detection & Monitoring
Log Indicators:
- SQL error messages in web server logs
- Multiple failed login attempts followed by admin access
- Unusual database queries from web application
Network Indicators:
- HTTP requests to admin/index.php with SQL patterns in parameters
- Unusual database traffic from web server
SIEM Query:
source="web_logs" AND uri="*admin/index.php*" AND (param="*userid=*'*" OR param="*userid=*%27*")
