Executive Summary

This vulnerability is a stored cross-site scripting (XSS) issue in the Phpgurukul Cyber Cafe Management System v1.0, specifically in the user management module. It occurs because the application does not properly sanitize or encode user input submitted via the uadd parameter in the add-users.php endpoint. An authenticated attacker can inject malicious JavaScript code that is stored persistently in the database. This malicious code executes when a privileged user clicks the View button on the view-allusers.php page.

Impact Analysis

This vulnerability can allow an attacker to execute arbitrary JavaScript code in the context of a privileged user's browser. This can lead to unauthorized actions such as stealing session cookies, performing actions on behalf of the privileged user, or defacing the application interface. Since the malicious script is stored persistently, it can repeatedly affect users who access the vulnerable page, potentially compromising sensitive information and system integrity.
