Microsoft IIS 5.0 WebDAV Malformed PROPFIND Request Remote DoS

This script is Copyright (C) 2001-2014 John Lampe


Synopsis :

The remote web server is vulnerable to a denial of service attack.

Description :

The remote version of the IIS web server contains a bug in its
implementation of the WebDAV protocol that could allow an attacker to
temporarily disable this service remotely.

To exploit this flaw, an attacker would require the ability to send a
malformed PROPFIND request to the remote host, although this would not
in turn necessarily require authentication.
