Microsoft Windows Server 2003 IIS 6.0 WebDAV PROPFIND Request Handling RCE (EXPLODINGCAN)

This script is Copyright (C) 2017 Tenable Network Security, Inc.


Synopsis :

The remote Windows host is affected by a remote code execution
vulnerability.

Description :

The remote host is running Windows Server 2003 and Internet
Information Services (IIS) 6.0 with WebDAV enabled. It is, therefore,
affected by a buffer overflow condition in the IIS WebDAV
service due to improper handling of the 'If' header in a PROPFIND
request. An unauthenticated, remote attacker can exploit this, via a
specially crafted request, to cause a denial of service condition or
the execution of arbitrary code.

EXPLODINGCAN is one of multiple Equation Group vulnerabilities and
exploits disclosed on 2017/04/14 by a group known as the Shadow
Brokers.

Solution :
