If a virtual host root is mapped to a UNC share, a backward slash "\" appended to an ASP or HTR extension in a URL request to that virtual host will cause Microsoft Internet Information Server to transmit full source code of the file back to a remote user. Files located on the local drive where IIS is installed is not affected by this vulnerability.
