"The remote host is running BlueDragon Server / Server JX, Java-based
servers for stand-alone deployment of CFML (ColdFusion Markup
Language) pages. 

The version of BlueDragon Server / Server JX installed on the remote
host fails to sanitize user-supplied input passed as part of the
filename before using it in a dynamically-generated error page.  An
unauthenticated attacker can exploit this issue to execute arbitrary
HTML and script code in a user's browser within the context of the
affected application. 

In addition, the server reportedly stops responding when it tries to
handle a request containing an MS-DOS device name with the '.cfm'
extension.");
