CVE-2024-27956 is a high severity vulnerability that has been identified in ValvePress Automatic (from n/a through version 3.92.), a popular web application. This vulnerability allows attackers to remotely execute malicious SQL commands by causing Improper Neutralization of Special Elements used in an SQL Command. Commonly known as SQL Injection, this vulnerability poses significant threats to the security and integrity of the affected systems.

Exploit Details

The vulnerability CVE-2024-27956 exists due to the improper neutralization of special elements such as single quotes, double quotes, and other important characters that are used in SQL commands. This results in the attacker being able to inject malicious SQL statements into the application, leading to unauthorized access, data modification, and potential data leak.

To demonstrate this issue, let's consider the following vulnerable code snippet

$userid = $_GET['userid'];
$query  = "SELECT * FROM users WHERE id = '".$userid."'";
$result = mysqli_query($connection, $query);

In this example, the attacker can manipulate the 'userid' parameter by adding a single quote and an additional SQL statement that changes the intended behavior of the query. Given the following request:

https://example.com/users?userid=1'; OR '1'='1

SELECT * FROM users WHERE id='1' OR '1'=='1'

The above query returns every record in the 'users' table, which demonstrates unauthorized access to sensitive data, leading to potential data breaches and other adverse impacts on the security of the web application.
