itsourcecode College Management System SQL Injection Vulnerability in Display Teacher File

A SQL injection vulnerability exists in the itsourcecode College Management System version 1.0, specifically within the admin/display-teacher.php file. The issue arises from the teacher_id parameter, which is not properly sanitized before being used in SQL queries. This flaw allows authenticated attackers to inject malicious SQL code, potentially leading to unauthorized database access, data manipulation, and exploitation of the underlying system.

Impact

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

Reproduction

To reproduce this vulnerability, log into the application and navigate to the admin/display-teacher.php page. Once there, the teacher_id parameter can be manipulated to inject SQL payloads. This can be done using a crafted GET request that includes the injected SQL code in the teacher_id parameter.

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.
