🎯 Exploit Status
Public exploit code available; SQL injection via registration form requires no authentication.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: Unknown
Vendor Advisory: https://www.campcodes.com/
Restart Required: No
Instructions:
1. Check vendor website for updates 2. If patch available, download and apply 3. Test registration functionality 4. Monitor for any issues
🔧 Temporary Workarounds
Input Validation and Sanitization
allImplement parameterized queries and input validation for full_name and username fields
Modify registration.php to use prepared statements: $stmt = $conn->prepare('INSERT INTO users (full_name, username) VALUES (?, ?)'); $stmt->bind_param('ss', $full_name, $username);
Web Application Firewall Rules
allBlock SQL injection patterns in registration.php requests
WAF rule: deny requests to /registration.php containing SQL keywords like UNION, SELECT, INSERT, DELETE, DROP, OR 1=1
🧯 If You Can't Patch
- Block external access to /registration.php using firewall rules or web server configuration
- Implement network segmentation to isolate the Hospital Management System from sensitive networks
🔍 How to Verify
Check if Vulnerable:
Test registration.php with SQL injection payloads in full_name or username fields (e.g., ' OR '1'='1) and observe database errors or unexpected behaviorCheck Version:
Check system documentation or admin panel for version information; typically displayed in footer or about pageVerify Fix Applied:
Attempt SQL injection tests after fixes; successful fix should return proper error handling without database interaction📡 Detection & Monitoring
Log Indicators:
- Multiple failed registration attempts with SQL keywords
- Unusual database queries from web server IP
- Error logs showing SQL syntax errors
Network Indicators:
- HTTP POST requests to /registration.php containing SQL injection patterns
- Unusual outbound database connections from web server
SIEM Query:
source="web_logs" AND uri="/registration.php" AND (message="*UNION*" OR message="*SELECT*" OR message="*OR 1=1*")
