Code-projects Simple Stock System 1. has been identified to be vulnerable to SQL injection attacks, according to the Common Vulnerabilities and Exposures (CVE) database under the identifier CVE-2024-24095. This post aims to provide more details on this vulnerability, including the exploit details, a code snippet to help better understand the issue, and links to original references.

Overview of the Vulnerability

If you are unfamiliar with SQL injection, it is a type of cyberattack that allows users to manipulate database queries and request sensitive data from a web application's underlying database. It potentially provides an attacker with unauthorized access to sensitive data like user credentials or personal information.

In Code-projects Simple Stock System 1., an attacker can exploit this vulnerability to inject malicious SQL code into user input fields, leading to data loss, unauthorized access to sensitive information, or even complete control over the underlying database system.

Code Snippet

Below is a simple demonstration of a vulnerable code snippet in the application that allows an SQL injection attack.

// PHP code for handling user input:
$username = $_GET['username'];
$password = $_GET['password'];

$sql = "SELECT * FROM users WHERE username = '{$username}' AND password = '{$password}'";
$result = mysqli_query($conn, $sql);

In this code, the application receives the username and password from user input and builds a SQL query without properly validating or sanitizing the input. This would allow an attacker to inject malicious SQL code into the input fields, leading to the exploit.

Exploit Details

For instance, an attacker can exploit the vulnerability by providing malicious inputs like the following:

username: 'admin' --
password: 'any_text'

The resulting SQL query would look like this

SELECT * FROM users WHERE username = 'admin' --' AND password = 'any_text';

The double hyphen -- is a comment in SQL, causing the remainder of the query to be ignored. As a result, the attacker can bypass the password check and gain unauthorized access.

How to Fix the Issue

To mitigate this vulnerability, the application developers should implement proper input validation and sanitization using prepared statements or parameterized queries. Here is a sample code snippet using prepared statements with mysqli:

$stmt = $conn->prepare("SELECT * FROM users WHERE username = ? AND password = ?");
$stmt->bind_param("ss", $username, $password);

$username = $_GET['username'];
$password = $_GET['password'];

$stmt->execute();

Conclusion

In short, Code-projects Simple Stock System 1. is vulnerable to SQL injection attacks under the identifier CVE-2024-24095. The vulnerability can lead to unauthorized access, data leakage, and database manipulation by an attacker. It is thus essential for developers to employ proper validation and sanitation techniques like parameterized queries, prepared statements, or using stored procedures to mitigate this vulnerability.
