🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: Unknown
Vendor Advisory: https://gitee.com/Kenj_Frog/company-financial-management/issues/IBM6D9
Restart Required: Yes
Instructions:
1. Monitor Gitee repository for updates 2. Apply any available patches 3. Restart the application server 4. Verify the fix
🔧 Temporary Workarounds
Input Validation Filter
allImplement strict input validation for the 'sort' parameter to only allow expected values
Implement parameterized queries or input whitelisting in ShangpinleixingController.java
WAF Rule
allDeploy web application firewall rules to block SQL injection patterns
Configure WAF to detect and block SQL injection attempts on sort parameter
🧯 If You Can't Patch
- Isolate the system behind a firewall with strict network access controls
- Implement database user permission restrictions to limit potential damage
🔍 How to Verify
Check if Vulnerable:
Test the sort parameter with SQL injection payloads like ' OR '1'='1Check Version:
Check application version in deployment configuration or manifest filesVerify Fix Applied:
Verify that SQL injection attempts no longer succeed and parameterized queries are implemented📡 Detection & Monitoring
Log Indicators:
- Unusual SQL queries in database logs
- Multiple failed login attempts following SQL errors
- Unexpected database schema queries
Network Indicators:
- SQL keywords in HTTP parameters
- Unusual database connection patterns from application server
SIEM Query:
search 'SQL syntax error' OR 'SQL injection' in application logs AND source_ip=application_server
