🛠️ Fix & Mitigation

✅ Official Fix

Patch Version: Unknown

Vendor Advisory: Not available

Restart Required: No

Instructions:

No official patch available. Consider migrating to alternative hotel booking software or implementing workarounds.

🔧 Temporary Workarounds

Input Validation Filter

all

Implement server-side validation to sanitize h_room_type parameter input

Modify PHP code to validate h_room_type parameter using preg_match('/^[a-zA-Z0-9_]+$/', $h_room_type) or similar

Web Application Firewall

linux

Deploy WAF with SQL injection protection rules

Install and configure ModSecurity with OWASP Core Rule Set
Enable SQL injection detection rules

🧯 If You Can't Patch

  • Isolate the vulnerable system behind a reverse proxy with strict input filtering
  • Implement network segmentation to limit database access from the web application

🔍 How to Verify

Check if Vulnerable:

Test h_room_type parameter with SQL injection payloads like ' OR '1'='1

Check Version:

Check application files for version information; typically in readme.txt or configuration files

Verify Fix Applied:

Test with same payloads after implementing fixes; should return error or sanitized response

📡 Detection & Monitoring

Log Indicators:

  • Unusual SQL queries in database logs
  • Multiple failed login attempts following SQL injection patterns
  • Web server logs showing SQL keywords in h_room_type parameter

Network Indicators:

  • Unusual database traffic patterns from web server
  • SQL error messages in HTTP responses

SIEM Query:

source="web_logs" AND (h_room_type="*' OR*" OR h_room_type="*UNION*" OR h_room_type="*SELECT*" OR h_room_type="*DROP*")
