WinGate Invalid SMTP State Format String DoS

This script is Copyright (C) 2007-2016 Tenable Network Security, Inc.


Synopsis :

The remote proxy is affected by a denial of service vulnerability.

Description :

The remote host appears to be running WinGate, a Windows application
for managing and securing Internet access.

The version of WinGate installed on the remote host fails to sanitize
user-supplied input to its SMTP server component of format strings
before using it to log a problem. By connecting to the service and
issuing commands the server was not expecting, a remote attacker may
be able to force the service to an invalid state and crash the WinGate
service itself, thereby denying service to legitimate users.
