Microsoft IIS WebDAV Remote Authentication Bypass Vulnerability

As a result due to lack of security implementation check it will let the user fetch password protected directories without any valid authentications. Impact Level: Application

Due to the wrong implementation of UNICODE characters support (WebDAV extension) for Microsoft IIS Server which fails to decode the requested URL properly. Unicode character checks are being done after IIS Server internal security check, which lets the attacker execute any crafted UNICODE character in the HTTP requests to get information on any password protected directories without any authentication schema.
