🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: Unknown
Vendor Advisory: https://www.sourcecodester.com/
Restart Required: No
Instructions:
No official patch available. Consider migrating to alternative clinic management software or implementing custom fixes with proper input validation.
🔧 Temporary Workarounds
Input Validation and Sanitization
allImplement server-side input validation and parameterized queries for all user inputs, especially doctorname parameter.
Implement prepared statements: $stmt = $pdo->prepare('SELECT * FROM doctors WHERE name = ?'); $stmt->execute([$doctorname]);
Web Application Firewall (WAF)
allDeploy WAF rules to block SQL injection patterns targeting /doctor.php endpoint.
ModSecurity rule: SecRule ARGS:doctorname "@detectSQLi" "id:1001,phase:2,deny,status:403"
🧯 If You Can't Patch
- Isolate the system behind a reverse proxy with strict input filtering
- Implement network segmentation to limit database access from web server
🔍 How to Verify
Check if Vulnerable:
Test /doctor.php endpoint with SQL injection payloads like ' OR '1'='1 in doctorname parameter and observe database errors or unexpected behavior.Check Version:
Check application version in admin panel or review source code for version markersVerify Fix Applied:
Attempt SQL injection attacks against the doctorname parameter and verify they are blocked or sanitized without database errors.📡 Detection & Monitoring
Log Indicators:
- Unusual SQL syntax in access logs for /doctor.php
- Database error messages containing SQL fragments
- Multiple failed login attempts or unusual parameter values
Network Indicators:
- HTTP requests to /doctor.php with SQL keywords in parameters
- Unusual database query patterns from web server IP
SIEM Query:
source="web_access.log" AND uri="/doctor.php" AND (param="doctorname" AND value MATCHES "(?i)(union|select|insert|update|delete|drop|--|#|/*)")
