injection attack." );

"The remote host is running Thyme, a web-based calendar. 

The version of Thyme installed on the remote host fails to properly
sanitize user-supplied input to the 'eid' parameter of the
'event_view.php' script before using it to build a database query. 
Regardless of PHP's 'magic_quotes_gpc' setting, an unauthenticated
remote attacker can leverage this issue to launch SQL injection
attacks against the affected application, leading to discovery of
sensitive information, attacks against the underlying database, and
the like." );
