Advantech / BroadWin WebAccess webvrpcs.exe Service Remote Code Execution (uncredentialed check) (deprecated)

This script is Copyright (C) 2011-2018 Tenable Network Security, Inc.

Synopsis :

This plugin has been deprecated.

Description :

The Advantech / BroadWin WebAccess software installed on the remote
Windows host includes an RPC service (webvrpcs.exe) that listens
remotely on TCP port 4592. It is affected by two vulnerabilities :

- An overflow condition exists due to improper validation
of user-supplied input. An unauthenticated, remote
attacker can exploit this, via a specially crafted
request, to execute arbitrary code.

- An information disclosure vulnerability exists that
allows an unauthenticated, remote attacker to obtain the
security code value that protects the SCADA node via a
long string in an RPC request to TCP port 4592.

This plugin has been deprecated due to false positives.
