Siemens SIMATIC WinCC (TIA Portal) 13 < 13 SP1 Multiple Vulnerabilities (SSA-543623)

Medium Nessus Plugin ID 81578

Synopsis

An application running on the remote host is affected by multiple vulnerabilities.

Description

The remote host is running a version of Siemens SIMATIC WinCC (TIA Portal) 13.x prior to version 13 service pack 1 (1300.100.2201.15). It is, therefore, affected by multiple vulnerabilities :

- A flaw exists in the project administration application due to the use of a hardcoded encryption key. A remote attacker can extract this key and use it to perform a man-in-the-middle attack in order to gain access to the system. (CVE-2014-4686)

- A flaw exists in the remote management module in Multi Panels, Comfort Panels, and RT Advanced due to the transmission of weakly protected credentials over the network. A remote, man-in-the-middle attacker can capture the network traffic of the remote management module to gain access to credential information.
(CVE-2015-1358)

Solution

Upgrade to Siemens SIMATIC WinCC (TIA Portal) version 13 SP1 (1300.100.2201.15) or later.
