✅ Official Fix
Patch Version: Unknown
Vendor Advisory: https://www.sourcecodester.com/
Restart Required: No
Instructions:
1. Check vendor website for updates 2. If patch available, download and replace affected files 3. Test functionality after update
🔧 Temporary Workarounds
Input Validation and Sanitization
allImplement strict input validation and parameterized queries for the 'person' parameter
Replace raw SQL queries with prepared statements: $stmt = $pdo->prepare('DELETE FROM persons WHERE id = ?'); $stmt->execute([$person]);
Web Application Firewall Rules
allDeploy WAF rules to block SQL injection patterns targeting delete.php
ModSecurity rule: SecRule ARGS:person "@detectSQLi" "id:1001,phase:2,deny,status:403"
🧯 If You Can't Patch
- Disable or restrict access to /endpoint/delete.php via web server configuration or firewall rules
- Implement network segmentation to isolate the vulnerable system from sensitive data and critical infrastructure
🔍 How to Verify
Check if Vulnerable:
Test the /endpoint/delete.php endpoint with SQL injection payloads like: person=1' OR '1'='1Check Version:
Check application files for version information or review source code commentsVerify Fix Applied:
Verify that SQL injection payloads no longer execute and return appropriate error responses📡 Detection & Monitoring
Log Indicators:
- Unusual SQL error messages in application logs
- Multiple DELETE requests with suspicious parameter values
- Failed authentication attempts followed by delete.php access
Network Indicators:
- HTTP requests to delete.php with SQL keywords in parameters
- Unusual database query patterns from web server IP
SIEM Query:
source="web_logs" AND uri_path="/endpoint/delete.php" AND (param="person" AND value MATCHES "(?i)(union|select|insert|delete|update|drop|--|#|/*)")
