itsourcecode University Management System SQL Injection Vulnerability in att_add.php

A SQL injection vulnerability has been identified in the itsourcecode University Management System version 1.0, specifically in the file att_add.php. This vulnerability arises from inadequate validation of user input in the 'name' parameter, allowing attackers to inject malicious SQL queries. The exploitation of this vulnerability could lead to unauthorized access to the database, manipulation or deletion of data, and exposure of sensitive information. Notably, this vulnerability can be exploited remotely without any authentication.

Impact

Exploitation of this vulnerability allows for SQL injection, enabling attackers to manipulate database queries. This could result in unauthorized database access, leakage or modification of sensitive data, and potential disruption of services.

Reproduction

The vulnerability can be reproduced by sending a POST request to the att_add.php file with a crafted 'name' 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 separate SQL code from user input, ensuring that injected data is not executed as part of a SQL command. Additionally, input validation and filtering should be applied to confirm that user data meets expected formats. Minimizing database user permissions and conducting regular security audits can further enhance the application's security.
