"The remote host is running Fusebox, a framework for building web-based
applications in Cold Fusion and PHP. 

The installed web application appears to have been created using
Fusebox in such a way that it fails to sanitize user-supplied input to
the 'fuseaction' parameter before using it in dynamically-generated
webpages. 

Note that this flaw may not be specific to the Fusebox framework, per
se, but instead be an implementation issue since Fusebox itself does
not generate any HTML, but lets the developer control all output.");
