source: https://www.securityfocus.com/bid/17306/info PhxContacts 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 an SQL query. A successful exploit could allow an attacker to compromise the application, access or modify data, or exploit vulnerabilities in the underlying database implementation. PhxContacts 0.93.1 and prior are vulnerable; other versions may also be affected. http://www.example.com/contact_view.php?id_contact=[sql]
