The remote host is vulnerable to a flaw which allows attackers to retrieve sensitive files.
The remote host is running Macromedia ColdFusion, a web application server. This version of Macromedia is vulnerable to a flaw in the way that it stores its class files. Specifically, a flaw in the Macromedia ColdFusion MX Updater causes compiled Java classes to be stored in the '/WEB-INF/cfclasses' directory. A remote attacker can retrieve the files and run a Java decompiler in order to decompile the binary code into human-readable format.
Upgrade to ColdFusion 7.0 MX or higher.. There is also a workaround available for version 6.1.
