Affected systems running the vulnerable PHP application are at immediate risk of data theft and database compromise.

Technical ContextAI

The vulnerability affects the PHP-based Free Hotel Reservation System developed by itsourcecode, specifically in the file /hotel/admin/mod_reports/index.php.

As an immediate mitigation, administrators should implement a Web Application Firewall (WAF) with SQL injection prevention rules, particularly monitoring the /hotel/admin/mod_reports/index.php endpoint and the 'Home' parameter. Additionally, apply principle of least privilege to the database user account used by the application, restrict network access to the admin interface through IP allowlisting, and consider temporarily disabling the reports module if not business-critical until a vendor patch becomes available.
