Multiple SQL injection vulnerabilities in the Hotel Booking Reservation System (aka HBS) for Joomla! allow remote attackers to execute arbitrary SQL commands via the id parameter in a showhoteldetails action to index.php in the (1) com_allhotels or (2) com_5starhotels module. NOTE: some of these details are obtained from third party information.
Improper Neutralization of Special Elements used in an SQL Command The product constructs all or part of an SQL command using externally-influenced input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could modify the intended SQL command when it is sent to a downstream component. Without sufficient removal or quoting of SQL syntax in user-controllable inputs, the generated SQL query can cause those inputs to be interpreted as SQL instead of ordinary user data.
