Land Down Under 700/701/800/801 - 'events.php?c' SQL Injection

source: https://www.securityfocus.com/bid/14685/info
 
Land Down Under is prone to multiple SQL injection vulnerabilities. These issues are due to a failure in the application to properly sanitize user-supplied input before using it in SQL queries.
 
Successful exploitation could result in a compromise of the application, disclosure or modification of data, or may permit an attacker to exploit vulnerabilities in the underlying database implementation.
