Description

The vulnerability allows a remote attacker to execute arbitrary SQL queries in database.

The vulnerability exists due to insufficient sanitization of user-supplied data passed via "User" and "pass" parameters of the user registration function. A remote non-authenticated attacker can send a specially crafted HTTP POST request to the "/objects/userCreate.json.php" URL and execute arbitrary SQL commands within the application database.

Successful exploitation of this vulnerability may allow a remote attacker to read, delete, modify data in database and gain complete control over the affected application.
