Siemens SIMATIC WinCC (TIA Portal) < 14 Unquoted Service Path Local Privilege Escalation (SSA-701708)

This script is Copyright (C) 2016-2017 Tenable Network Security, Inc.


Synopsis :

An application installed on the remote host is affected by a local
privilege escalation vulnerability.

Description :

The version of Siemens SIMATIC WinCC (TIA Portal) installed on the
remote Windows host is prior to version 14. It is, therefore, affected
by a local privilege escalation vulnerability due to an unquoted
service path. A local attacker can exploit this, via a malicious
executable in the root path, to elevate privileges.

Note that Nessus has not tested for this issue but has instead relied
only on the application's self-reported version number.
