🔧 Temporary Workarounds
Input Validation and Sanitization
allAdd parameterized queries or proper input validation for the editid parameter in edit-class.php
Modify /admin/edit-class.php to use prepared statements: $stmt = $conn->prepare('SELECT * FROM classes WHERE id = ?'); $stmt->bind_param('i', $_GET['editid']);
Web Application Firewall Rules
allBlock SQL injection patterns targeting the editid parameter
WAF rule: SecRule ARGS:editid "@detectSQLi" "id:1001,phase:2,deny"
🧯 If You Can't Patch
- Block external access to /admin/edit-class.php via firewall rules or web server configuration
- Implement strict network segmentation to isolate the vulnerable system from sensitive data
🔍 How to Verify
Check if Vulnerable:
Test the /admin/edit-class.php?editid=1' endpoint for SQL error responses or time-based delays with malicious payloads
Check Version:
Check software version in admin panel or readme files
Verify Fix Applied:
Attempt SQL injection payloads against the patched endpoint and verify they are rejected or sanitized
📡 Detection & Monitoring
Log Indicators:
- SQL syntax errors in web server logs
- Unusual database queries from web application user
- Multiple failed login attempts followed by edit-class.php access
Network Indicators:
- HTTP requests to /admin/edit-class.php with SQL keywords in parameters
- Unusual outbound database connections from web server
SIEM Query:
source="web_logs" AND uri="/admin/edit-class.php" AND (param="editid" AND value MATCHES "'.*[Ss][Ee][Ll][Ee][Cc][Tt].*'" OR value MATCHES ".*--.*")
