Executive brief
itsourcecode Sales and Inventory System is a PHP-based application used for managing sales and inventory operations. A SQL injection vulnerability in the user edit functionality allows authenticated attackers to manipulate database queries, potentially exposing sensitive data, modifying records, or gaining unauthorized system access.
Technical details
A SQL injection vulnerability exists in the `/pages/us_edit1.php` file where the 'id' parameter fails to properly sanitize or validate user input before using it in SQL queries. The vulnerability requires valid authentication credentials and network access to the application. An attacker can inject malicious SQL through the 'id' parameter to execute arbitrary database operations, read sensitive data, modify records, or potentially execute system commands depending on database permissions. The vulnerability is fixed by implementing prepared statements with parameter binding, strict input validation, and minimal database user permissions.
