A critical SQL injection vulnerability, CVE-2022-43213, has been discovered in Billing System Project v1.. This vulnerability is found within the editorder.php file, which is used to manage orders within the application. An attacker can potentially exploit this vulnerability to execute arbitrary SQL queries via the "id" parameter. This can lead to unauthorized access, extraction of sensitive data, and even complete control over the affected system.

Understanding SQL Injection

SQL injection is a common web application vulnerability where an attacker sends malicious SQL commands to a database. These commands are executed by exploiting vulnerabilities in the application's code, which allow user input to be included in the database queries. The attacker’s goal is often to steal data, modify the underlying database structure, or compromise the server where the database is hosted. SQL injection can be particularly dangerous because it often leads to full system compromise.

Vulnerability Analysis

The vulnerability is found within the editorder.php file in the Billing System Project v1.. This file is responsible for managing orders and contains a script to retrieve the order details based on the provided "id" parameter. The "id" parameter is then used in a SQL query without proper sanitization or validation, leading to a SQL injection vulnerability.

Here's the affected code snippet

  $id = intval($_GET['id']);
  $getorder = mysqli_query($conn,"SELECT * FROM orders WHERE id='$id'");
  $order = mysqli_fetch_assoc($getorder);

As seen above, the "id" parameter ($_GET['id']) is directly included in the SQL query, and its value is not sanitized or validated before being used. This allows an attacker to insert malicious SQL queries and execute them in the database.

Exploit Details

An attacker can make use of this vulnerability by submitting a crafted request to the editorder.php file with the malicious SQL query in the "id" parameter:

http://target.com/editorder.php?id=<malicious SQL query>

For example, an attacker could submit the following request to retrieve all user details from the "users" table:

http://target.com/editorder.php?id=1'; UNION SELECT 1,2,3,4 FROM users--

This would cause the SQL query used in the vulnerable script to become

SELECT * FROM orders WHERE id='1' UNION SELECT 1,2,3,4 FROM users--'

As a result, the attacker can retrieve sensitive information from the "users" table, which may include email addresses, passwords, and more.

It is important to note that the impact of this vulnerability could extend beyond data extraction. Depending on the privileges assigned to the database user, an attacker could potentially add, modify, or delete data as well.


To mitigate this vulnerability in your Billing System Project, the following recommendations should be implemented:

1. Update the affected application to a patched version. It is essential to keep your software up to date to prevent known vulnerabilities from being exploited.
2. Use prepared statements or parameterized queries to avoid SQL injection. This will prevent malicious user input from being directly included in the SQL query.

The vulnerability was reported and documented by security researchers
