How the Exploit Works
The vulnerability exists in the user_order_customer_update.php file. It allows an attacker to manipulate SQL queries by injecting malicious SQL statements via the order_id POST parameter. Consequently, this could enable an attacker to read sensitive data from the database, modify database data (Insert/Update/Delete), execute administration operations on the database (such as shutdown the DBMS), recover the content of a given file present on the DBMS file system, or even issue commands to the operating system.
Conceptual Example Code
Here’s a conceptual example of how this vulnerability might be exploited. Please note that this is for educational purposes only and should not be used for malicious activities.
POST /user_order_customer_update.php HTTP/1.1
Host: target.example.com
Content-Type: application/x-www-form-urlencoded
order_id=1;DROP TABLE users;--In the above example, the attacker sends a POST request with a malicious SQL command (`DROP TABLE users;–`) injected via the order_id parameter. If the application is vulnerable, this command will cause the users table in the database to be deleted.
Recommended Mitigation
The most effective solution to this vulnerability is to apply the vendor-provided patch. Until the patch can be applied, a temporary mitigation measure could be the deployment of a Web Application Firewall (WAF) or Intrusion Detection System (IDS) that can filter out or detect SQL injection attacks at the network level. In the long run, it is always advisable to follow secure coding practices, such as input validation, parameterized queries, or ORM frameworks, to prevent SQL injection vulnerabilities.
