🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: Unknown
Vendor Advisory: https://www.sourcecodester.com/
Restart Required: No
Instructions:
No official patch available. Consider upgrading to a newer version if available or implementing workarounds.
🔧 Temporary Workarounds
Input Validation Filter
allAdd parameter validation to only accept numeric values for the ID parameter
Modify /index.php/stock/vendordetails to validate ID parameter: if(!is_numeric($_GET['ID'])) { die('Invalid parameter'); }
WAF Rule Implementation
allDeploy web application firewall rules to block SQL injection patterns
Add WAF rule: SecRule ARGS:ID "@rx (?i)(union|select|insert|update|delete|drop|create|alter)" "id:1001,phase:2,deny,status:403,msg:'SQL Injection Attempt'"
For ModSecurity: SecRule ARGS "@detectSQLi" "id:1002,phase:2,deny"
🧯 If You Can't Patch
- Implement network segmentation to restrict access to the vulnerable system
- Deploy database monitoring to detect unusual SQL queries
🔍 How to Verify
Check if Vulnerable:
Test the endpoint with SQL injection payloads: curl 'http://target/index.php/stock/vendordetails?ID=1' AND '1'='1'Check Version:
Check system version in admin panel or readme filesVerify Fix Applied:
Test with same payloads after implementing fixes - should return error or no data📡 Detection & Monitoring
Log Indicators:
- Unusual SQL error messages in application logs
- Multiple requests with SQL keywords in parameters
- Requests to /index.php/stock/vendordetails with non-numeric ID values
Network Indicators:
- HTTP requests containing SQL keywords (UNION, SELECT, etc.) in URL parameters
- Unusual database query patterns from application server
SIEM Query:
source="web_logs" AND (url="*vendordetails*" AND (param="*union*" OR param="*select*" OR param="*' OR '1'='1*"))
