How the Exploit Works
The vulnerability lies in the lack of proper input validation of several parameters in the user/registration.php file. By exploiting this vulnerability, an attacker can inject malicious SQL code into the affected parameters ‘fullname’, ’email’, and ‘contactno’. The malicious code is then executed by the database, potentially leading to unauthorized data access, data manipulation, or even system control.
Conceptual Example Code
Here is a conceptual example of an HTTP request that could exploit the vulnerability:
POST /user/registration.php HTTP/1.1
Host: target.example.com
Content-Type: application/x-www-form-urlencoded
fullname=a'; DROP TABLE users; --&email=b&contactno=cThis request contains a SQL Injection in the ‘fullname’ parameter. The SQL command ‘DROP TABLE users;’ will delete the ‘users’ table from the database if executed.
Mitigation
To mitigate this vulnerability, it is recommended to apply the vendor patch as soon as it becomes available. As an interim measure, a Web Application Firewall (WAF) or Intrusion Detection System (IDS) can be used to detect and block attempts to exploit this vulnerability.
