Configuration
The remote web server leaks a private IP address through the WebDAV interface. If this web server is behind a Network Address Translation (NAT) firewall or proxy server, then the internal IP addressing scheme has been leaked. This is typical of IIS 5.0 installations that are not configured properly.
