🛠️ 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 input validation to sanitize the ID parameter in /edit.php
Modify /edit.php to validate ID parameter: if(!is_numeric($_GET['ID'])) { die('Invalid input'); }
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:'SQLi attempt detected'"
🧯 If You Can't Patch
- Isolate the system behind a firewall with strict access controls
- Implement network segmentation to limit database access from the web server
🔍 How to Verify
Check if Vulnerable:
Test /edit.php with SQL injection payloads like: /edit.php?ID=1' OR '1'='1
Check Version:
Check system version in admin panel or readme files
Verify Fix Applied:
Test with same payloads after implementing fixes - should return error or no database interaction
📡 Detection & Monitoring
Log Indicators:
- Unusual SQL queries in database logs
- Multiple failed login attempts from single IP
- Requests to /edit.php with SQL keywords in parameters
Network Indicators:
- HTTP requests containing SQL keywords (UNION, SELECT, etc.) in URL parameters
