Sielco Sistemi Winlog Pro < 2.07.01 TCP/IP Server Runtime.exe Packet Handling Remote Overflow

This script is Copyright (C) 2011-2015 Tenable Network Security, Inc.

Synopsis :

The remote Windows host contains a SCADA application that is affected
by a buffer overflow vulnerability.

Description :

The installed version of Winlog Lite or Winlog Pro from Sielco Sistemi
is earlier than 2.07.01 and thus reportedly has a buffer overflow in
its 'Runtime.exe' component that listens on TCP port 46823 if the 'Run
TCP/IP server' option is enabled for a project.

Using a specially crafted packet with opcode 0x02, an unauthenticated
remote attacker can leverage this issue to overflow a temporary stack
buffer of about 60 bytes and possibly execute arbitrary code.

Solution :

Upgrade to Winlog version 2.07.01 or later.
