🔍 How to Verify
Check if Vulnerable:
Check if running novel-cloud version 1.4.0 and examine BookInfoMapper.xml for vulnerable RestResp functionCheck Version:
Check application configuration files or deployment manifests for version informationVerify Fix Applied:
Test SQL injection attempts against the RestResp endpoint to confirm they are blocked📡 Detection & Monitoring
Log Indicators:
- Unusual SQL query patterns in application logs
- Multiple failed login attempts or parameter manipulation attempts
Network Indicators:
- SQL keywords in HTTP parameters (SELECT, UNION, INSERT, etc.)
- Unusual database connection patterns
SIEM Query:
