WebWasher Classic Server Mode Arbitrary Proxy CONNECT Request

This script is Copyright (C) 2005-2011 Tenable Network Security, Inc.


Synopsis :

The remote service is vulnerable to an access control breach.

Description :

There is a flaw in the remote WebWasher Proxy. The Proxy, when issued
a CONNECT command for 127.0.0.1 (or localhost/loopback), will comply with
the request and initiate a connection to the local machine.

This bypasses any sort of firewalling as well as gives access to local
applications which are only bound to the loopback.
