Code-Projects Exam Form Submission SQL Injection Vulnerability

A critical SQL injection vulnerability has been identified in Code-Projects Exam Form Submission version 1.0, specifically within the file '/admin/delete_s1.php'. This vulnerability arises from inadequate validation of user input in the 'id' parameter, allowing attackers to inject malicious SQL queries. Exploitation of this vulnerability could lead to unauthorized access to the database, manipulation or deletion of data, and exposure of sensitive information. Notably, this vulnerability can be exploited remotely without any authentication.

Impact

Exploitation of this vulnerability allows for SQL injection, where attackers can manipulate database queries to gain unauthorized access to the database, extract sensitive information, modify or delete data, and potentially disrupt services.

Reproduction

The vulnerability can be reproduced by sending a crafted HTTP request to the '/admin/delete_s1.php' file with an injected payload in the 'id' parameter. This payload should be designed to exploit the time-based blind SQL injection vulnerability, such as by using a SQL injection payload that includes a time delay command, which can be used to verify the injection and potentially extract database information.

Remediation

It is recommended to use prepared statements and parameter binding to prevent SQL injection, validate and filter user input, minimize database user permissions, and conduct regular security audits.
