itsourcecode College Management System SQL Injection Vulnerability in Student Fee Management

A SQL injection vulnerability exists in the itsourcecode College Management System version 1.0, specifically within the admin/student-fee.php file. The issue arises because the application does not properly sanitize the roll_no parameter, allowing authenticated users to inject malicious SQL queries. This vulnerability can be exploited remotely, potentially leading to unauthorized database access, data manipulation, and disruption of service.

Impact

Exploitation of this vulnerability allows for SQL injection, where an attacker can manipulate database queries. This could lead to unauthorized data access, data modification, and in some cases, executing administrative operations on the database.

Reproduction

To reproduce this vulnerability, log into the application with valid credentials. Then, send a POST request to the /admin/student-fee.php file with the roll_no parameter. The injection can be tested using time-based blind SQL injection techniques, such as using a payload that includes a sleep command, or by performing a UNION-based injection to extract data.

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 that user input conforms to expected formats. Minimizing database user permissions and conducting regular security audits can also help mitigate such vulnerabilities.
