PHPGurukul Hostel Management System SQL Injection Vulnerability in Students Management File

A critical SQL injection vulnerability has been identified in PHPGurukul Hostel Management System version 1.0. The issue resides in the file '/admin/students.php', where the 'search_box' parameter is manipulated to inject malicious SQL queries. This vulnerability allows remote attackers to gain unauthorized access to the database, potentially leading to data modification, deletion, or exposure of sensitive information. The vulnerability arises from inadequate input validation, allowing attackers to manipulate SQL queries and execute unauthorized database operations. Notably, no authentication is required to exploit this vulnerability.

Impact

Exploitation of this vulnerability allows attackers to execute arbitrary SQL commands, potentially leading to unauthorized database access, data manipulation or deletion, and exposure of sensitive information. The vulnerability could also be exploited to execute administrative operations on the database or application.

Reproduction

The vulnerability can be reproduced by sending a POST request to '/admin/students.php' with the 'search_box' parameter. The injected SQL payload can be crafted to exploit the application's SQL query handling, such as by using boolean-based blind injection techniques or error-based injection to extract database information.

Remediation

It is recommended to implement prepared statements and parameter binding to prevent SQL injection attacks. Additionally, input validation and filtering should be applied to ensure that user input conforms to expected formats. Minimizing database user permissions and conducting regular security audits can also help mitigate the risk of SQL injection vulnerabilities.
