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

Medium Nessus Plugin ID 95716

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.

Solution

Upgrade to Siemens SIMATIC WinCC (TIA Portal) version 14 or later.
