Introduction:

A potentially devastating vulnerability, known as CVE-2024-1826, has recently been discovered to exist in the popular Code-Projects Library System 1.. This flaw has been classified as critical, and if exploited, it could lead to serious consequences. The library system in question has a wide number of users and applications, so addressing this issue is of the utmost importance.

Details

The vulnerability affects an unspecified section of the code in the file Source/librarian/user/student/login.php. By manipulating the 'username' and 'password' arguments in a specific way, an attacker could potentially gain unauthorized access to the system through the use of a SQL Injection technique. Essentially, this means that a malicious individual could bypass the standard login procedure and manipulate the underlying database.

This SQL Injection attack could be launched remotely, which further emphasizes the severity of this vulnerability. The full details of how to exploit this vulnerability have already been disclosed to the public, making it crucial that users of the Code-Projects Library System 1. take action to rectify this vulnerability as soon as possible. The identifier for this critical vulnerability is recognized as VDB-254614.

Code Snippet

The following is an example of a flawed code snippet from the Source/librarian/user/student/login.php file:

<?php 
$username = $_POST['username'];
$password = $_POST['password'];

$query = "SELECT * FROM students WHERE username = '$username' AND password = '$password'";
$result = mysql_query($query);

if (mysql_num_rows($result) > ) {
  // User successfully logged in
} else {
  // Invalid login attempt
}
?>

The vulnerable code utilizes the user-supplied 'username' and 'password' variables to construct an SQL query directly. This allows an attacker to inject malicious SQL code, potentially leading to devastating consequences.

Mitigation:

To protect your system from this vulnerability, the most straightforward solution is to utilize prepared statements. Prepared statements separate the user-supplied data from the SQL query, which consequently reduces the chance of a successful SQL Injection attack. Below is an example of a secure implementation using prepared statements:

<?php 
$username = $_POST['username'];
$password = $_POST['password'];

$stmt = $mysqli->prepare("SELECT * FROM students WHERE username = ? AND password = ?");
$stmt->bind_param("ss", $username, $password);
$stmt->execute();
$result = $stmt->get_result();

if ($result->num_rows > ) {
  // User successfully logged in
} else {
  // Invalid login attempt
}
?>
