Hotel and Lodge Management System CVE-2025-11405

No vendor-released patch identified at time of analysis. The primary mitigation is to upgrade to a patched version if the vendor releases one, or contact SourceCodester directly for security guidance. Immediate compensating controls include implementing prepared statements (parameterized queries) in /del_tax.php and all SQL-executing endpoints to prevent injection, restricting the del_tax.php endpoint to trusted internal networks or administrative users only via firewall/WAF rules, and validating and sanitizing all user input parameters (especially ID) using strict allowlist validation (e.g., accepting only numeric values if ID is a primary key). Additionally, apply least-privilege database credentials - the PHP application should use a database user with only SELECT and DELETE permissions on the tax table, not broader administrative privileges. Web application firewalls should be configured to block SQL injection patterns. The trade-off of network restriction is reduced functionality for legitimate remote access, which may be acceptable for an internal hotel management system.
