🛠️ 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 and Parameterized Queries
allImplement proper input validation and use parameterized queries in /view_result.php
Modify PHP code to use prepared statements: $stmt = $conn->prepare('SELECT * FROM results WHERE id = ?'); $stmt->bind_param('i', $id);
Web Application Firewall (WAF)
allDeploy WAF rules to block SQL injection patterns
Add WAF rule: SecRule ARGS:id "@detectSQLi" "id:1001,phase:2,deny"
🧯 If You Can't Patch
- Restrict access to /view_result.php to authenticated users only
- Implement network segmentation to isolate the system from untrusted networks
🔍 How to Verify
Check if Vulnerable:
Test /view_result.php with SQL injection payloads like: /view_result.php?id=1' OR '1'='1Check Version:
Check system version in admin panel or readme filesVerify Fix Applied:
Test with same payloads after implementing parameterized queries - should return error or no data📡 Detection & Monitoring
Log Indicators:
- Unusual SQL errors in PHP logs
- Multiple requests to /view_result.php with suspicious ID parameters
- Database query errors containing single quotes or SQL keywords
Network Indicators:
- HTTP requests to /view_result.php with SQL injection patterns in parameters
- Unusual database connection patterns from web server
SIEM Query:
source="web_logs" AND uri="/view_result.php" AND (param_id CONTAINS "'" OR param_id CONTAINS "OR" OR param_id CONTAINS "UNION")
