vCard PRO - 'search.php?event_id' SQL Injection

source: https://www.securityfocus.com/bid/18699/info
   
VCard PRO 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.
   
A successful exploit could allow an attacker to compromise the application, access or modify data, or exploit vulnerabilities in the underlying database implementation.
