PHPGurukul Rail Pass Management System SQL Injection Vulnerability

A critical SQL injection vulnerability has been identified in the PHPGurukul Rail Pass Management System version 1.0. The issue resides in the file '/admin/search-pass.php', where the 'searchdata' parameter is manipulated to inject malicious SQL queries. This vulnerability can be exploited remotely, allowing attackers to access and manipulate the database without authorization.

Impact

Exploitation of this vulnerability could lead to unauthorized database access, allowing attackers to read, modify, or delete data. Additionally, it could result in executing administrative operations on the database, potentially compromising the entire application.

Reproduction

The vulnerability can be reproduced by sending a POST request to '/admin/search-pass.php' with a crafted 'searchdata' parameter that includes malicious SQL payloads. This can be done using tools like sqlmap, which automates the process of finding and exploiting SQL injection vulnerabilities.

Remediation

To address this vulnerability, it is recommended to implement prepared statements and parameter binding to prevent SQL injection. Additionally, input validation and filtering should be applied to ensure that user input is properly sanitized before being used in SQL queries. Minimizing database user permissions can also help reduce the impact of such vulnerabilities.
