PHPGurukul Directory Management System SQL Injection Vulnerability

A SQL injection vulnerability has been identified in PHPGurukul Directory Management System version 1.0. The issue resides in the Search component, specifically within the '/dms/index.php' file. The vulnerability is triggered by manipulating the 'searchdata' parameter, allowing attackers to inject malicious SQL queries. This exploitation can be done remotely, without any authentication.

Impact

Exploitation of this vulnerability allows attackers to execute arbitrary SQL commands, potentially leading to unauthorized database access, data manipulation, and access to sensitive information.

Reproduction

The vulnerability can be reproduced by sending a POST request to '/dms/searchdata.php' with the 'searchdata' parameter. Injecting a payload that exploits the SQL injection vulnerability, such as a time-based blind injection or a UNION-based injection, will demonstrate the vulnerability.

Remediation

It is recommended to use prepared statements and parameter binding to prevent SQL injection. Additionally, input validation and filtering should be implemented to ensure user input conforms to expected formats. Minimizing database user permissions and conducting regular security audits are also advisable.
