The version of MyBB installed on the remote host is affected by a SQL injection vulnerability due to improper sanitization of user-supplied input to the ‘rating’ parameter of the ratethread.php script. A remote attacker can exploit this issue to manipulate SQL queries, resulting in the disclosure of sensitive information and modification of data.
