Code-Projects Exam Form Submission SQL Injection Vulnerability

A critical SQL injection vulnerability has been identified in the Code-Projects Exam Form Submission version 1.0, specifically in the file '/admin/update_s5.php'. The vulnerability arises from inadequate validation of the 'credits' parameter, allowing attackers to inject malicious SQL queries. This exploitation can be performed remotely, without any authentication, potentially leading to unauthorized database access, data manipulation, and exposure of sensitive information.

Impact

Exploitation of this vulnerability allows for SQL injection, enabling attackers to interfere with the application's database queries. This could lead to unauthorized data access, data modification or deletion, and in some cases, executing administrative operations on the database.

Reproduction

The vulnerability can be reproduced by sending a POST request to '/admin/update_s5.php' with a crafted 'credits' parameter that includes malicious SQL code. This payload can exploit the SQL injection vulnerability by, for example, using time-based blind SQL injection techniques to manipulate the database.

Remediation

It is recommended to implement prepared statements and parameter binding to prevent SQL injection. Additionally, input validation and filtering should be applied to ensure user input conforms to expected formats. Minimizing database user permissions and conducting regular security audits are also advisable.
