Code-Projects Scholars Tracking System SQL Injection Vulnerability in Delete User Function

A SQL injection vulnerability has been identified in Code-Projects Scholars Tracking System version 1.0. The issue resides in the '/admin/delete_user.php' file, where the 'id' parameter is manipulated, allowing attackers to inject malicious SQL queries. This vulnerability can be exploited remotely, without any authentication, potentially leading to unauthorized database access, data modification or deletion, and exposure of sensitive information.

Impact

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

Reproduction

To reproduce this vulnerability, send a GET request to the '/admin/delete_user.php' endpoint with a crafted 'id' parameter that includes SQL injection payloads. The injection can be verified by using payloads that, for example, extract database information or introduce a time-based delay, indicating successful exploitation.

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 can also help enhance overall security.
