High-Tech Bridge SA has discovered multiple vulnerabilities, which can be exploited by malicious people to conduct SQL injection attacks.
Input appended to the URL after multiple scripts is not properly sanitised within the "update_whosonline_reg()" and "update_whosonline_guest()" functions (includes/user_function.php) before being used in a SQL query. This can be exploited to manipulate SQL queries by injecting arbitrary SQL code.
