Campcodes Student Grading System SQL Injection Vulnerability

A critical SQL injection vulnerability has been identified in Campcodes Student Grading System version 1.0. The issue resides in the 'view_students.php' file, where the 'id' parameter is improperly sanitized, allowing remote attackers to manipulate SQL queries and potentially access or modify database information.

Impact

Exploitation of this vulnerability allows for SQL injection, where an attacker can interfere with the application's database queries. This could lead to unauthorized data access, data manipulation, or in some cases, executing administrative operations on the database.

Reproduction

To reproduce this vulnerability, send a POST request to 'view_students.php' with an 'id' parameter that includes a crafted SQL payload. The injection point is the 'id' parameter, which is used in a SQL query without proper validation or escaping. After the injection, the response will include the SQL injection payload in the SQL query response.
