Executive Summary

CVE-2025-9656 is a Cross Site Scripting (XSS) vulnerability in PHPGurukul Directory Management System version 2.0, specifically in the /admin/add-directory.php file. It occurs because the 'fullname' parameter is not properly sanitized, allowing attackers to inject malicious JavaScript code. This code executes in the browsers of users who view the affected page, potentially leading to session hijacking, unauthorized actions, and exposure of sensitive information. [1, 2, 3]

Detection Guidance

This vulnerability can be detected by testing the /admin/add-directory.php endpoint for cross-site scripting (XSS) in the 'fullname' parameter. A proof-of-concept POST request injecting a script payload such as fullname=<script>alert(1)</script> can be used to verify the vulnerability. Additionally, vulnerable targets can be identified using Google dorking with the query: inurl:admin/add-directory.php. [2, 3]

Mitigation Strategies

Immediate mitigation steps include employing prepared statements and parameter binding to separate user input from executable code, implementing rigorous input validation and filtering to ensure inputs conform to expected formats and block malicious content, and minimizing database user permissions by avoiding use of high-privilege accounts for routine operations. These measures help protect user data, prevent privilege escalation, and maintain system integrity by mitigating the XSS risk. [2, 1]
