Sun Java IDE Webserver IP Restriction Failure Vulnerability

These Java development applications include an http server for testing purposes. The server can be configured to only respond to requests from certain IP addresses, however the mechanism fails and any requests received are serviced. The server will allow read access to any file on the filesystem that it haas access to, all the way up to the root directory. In the Netbeans product, this is the default 'out of the box' configuration. In the Forte product. IP addresses must be added manually to a list of permitted clients. Once a single IP address is added, any requests regardless of source are responded to.
