itsourcecode College Management System SQL Injection Vulnerability in teacher-salary.php

A SQL injection vulnerability exists in the itsourcecode College Management System version 1.0, specifically within the admin/teacher-salary.php file. The issue arises from improper validation of the teacher_id parameter, allowing attackers to inject malicious SQL code. This vulnerability can be exploited remotely without authentication.

Impact

Exploitation of this vulnerability allows for SQL injection, enabling attackers to 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, send a POST request to the admin/teacher-salary.php page with the teacher_id parameter. Inject a payload that exploits the SQL injection vulnerability, such as one that uses time-based blind SQL injection techniques, like causing the database to sleep for a few seconds.

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.
