How the Exploit Works
A hacker exploiting this vulnerability would send a specially crafted POST request to the action.php endpoint of the Online Shopping System. The hacker would use the keyword POST parameter to inject SQL commands in the request, exploiting the lack of input sanitization. These injected commands could then be executed by the application’s database, potentially leading to unauthorized read or write access to sensitive data.
Conceptual Example Code
Here’s a conceptual example of how the vulnerability might be exploited:
POST /action.php HTTP/1.1
Host: target.example.com
Content-Type: application/x-www-form-urlencoded
keyword=' OR '1'='1'; DROP TABLE customers; --This example uses the SQL Injection to trick the application into executing a command that drops (deletes) the ‘customers’ table from the database. In a real-world scenario, the injected commands could be tailored to extract sensitive data or execute other malicious actions.
Mitigation and Prevention
Users are urged to apply the vendor’s patch as soon as possible to address this vulnerability. In the meantime, a Web Application Firewall (WAF) or Intrusion Detection System (IDS) can be used as temporary mitigation. It’s also crucial to always sanitize user-supplied input to prevent such vulnerabilities in the future.
