Executive brief
Rizwan17's inventory management system is a PHP application used to manage product catalogs, categories, brands, and customer orders. A critical flaw allows attackers to perform all inventory operations—adding/deleting products, creating fraudulent orders, and modifying categories—without logging in. An attacker can bypass authentication entirely via direct HTTP requests to the backend API, potentially causing data loss, fraud, and operational disruption.
Technical details
The vulnerability is a missing authentication/authorization flaw in the AJAX backend (includes/process.php). All business operations are protected only by checking for the presence of POST parameters, with no server-side session or user authorization verification. The vulnerable component is the DBOperation.addCategory function and related handlers that process category, product, brand, and order management requests. Attack vectors are network-based with no authentication or user interaction required; an unauthenticated remote attacker can send POST requests directly to includes/process.php to manipulate inventory data. The impact is complete application compromise: creation/deletion of products and categories, fraudulent order placement, and exposure to chained SQL injection vulnerabilities. The project uses rolling releases and has not yet responded to the issue report.
