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

high Nessus Plugin ID 81578


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


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.


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