🔧 Temporary Workarounds
Input Validation and Sanitization
allImplement strict input validation and parameterized queries for the editid parameter
Modify /admin/edit-course.php to use prepared statements with parameter binding
Web Application Firewall (WAF)
allDeploy WAF rules to block SQL injection patterns targeting editid parameter
Configure WAF to block SQL injection patterns in POST/GET parameters
🧯 If You Can't Patch
- Restrict access to /admin/edit-course.php using IP whitelisting or additional authentication
- Implement database-level controls: restrict application database user permissions to minimum required
🔍 How to Verify
Check if Vulnerable:
Test the editid parameter with SQL injection payloads like ' OR '1'='1 in /admin/edit-course.phpCheck Version:
Check software version in admin panel or configuration filesVerify Fix Applied:
Test with same SQL injection payloads and verify they are properly sanitized or rejected📡 Detection & Monitoring
Log Indicators:
- Unusual SQL error messages in web server logs
- Multiple failed login attempts followed by edit-course.php access
- SQL keywords (SELECT, UNION, etc.) in editid parameter values
Network Indicators:
- HTTP requests to /admin/edit-course.php with SQL injection patterns in parameters
SIEM Query:
source="web_server_logs" AND uri="/admin/edit-course.php" AND (param="editid" AND value MATCHES "(?i)(union|select|or|and|'|--|#)")
