PHPGurukul Cyber Cafe Management System Reflected Cross-Site Scripting Vulnerability

A reflected cross-site scripting vulnerability has been identified in PHPGurukul Cyber Cafe Management System version 1.0. The issue arises in the search.php file, where user input from the searchdata POST parameter is not properly sanitized before being displayed in the HTML response. This flaw allows attackers to inject and execute arbitrary JavaScript in the context of the user's browser. The vulnerability can be exploited remotely, without authentication, but requires user interaction.

Impact

Exploitation of this vulnerability allows for reflected cross-site scripting, where an attacker can inject malicious scripts that are executed in the context of the user's browser.

Reproduction

The vulnerability can be reproduced by sending a POST request to the search.php endpoint with a script payload in the searchdata parameter. The server will respond with the injected script executed as JavaScript, demonstrating the cross-site scripting vulnerability.

Remediation

User input should be properly encoded using the htmlspecialchars() function before being output in HTML. This can prevent the execution of injected scripts and mitigate the cross-site scripting vulnerability.
