A cross-site scripting (XSS) vulnerability has been identified in the itsourcecode Payroll Management System, specifically in version 1.0. The issue resides in the index.php file, where user input from the 'page' parameter is not properly sanitized before being displayed. This flaw allows attackers to inject and execute arbitrary JavaScript in the context of the user's browser session. The vulnerability can be exploited remotely, without authentication, by persuading a user to click on a crafted link.
It is recommended to implement input validation to reject special characters, use an allow-list approach, and apply output encoding techniques such as 'htmlspecialchars()' or 'htmlentities()'. Additionally, consider adding security headers like 'Content-Security-Policy' and 'X-XSS-Protection'.
