Synopsis

An application installed on the remote host is affected by multiple denial of service vulnerabilities.

Description

The version of Siemens SIMATIC WinCC (TIA Portal) installed on the remote host is 13.x prior to 13 service pack 2 (1300.200.1001.1) or 14.x prior to 14 service pack 1 (1400.100.1201.1). It is, therefore, affected by multiple denial of service vulnerabilities :

- A denial of service vulnerability exists due to improper handling of PROFINET DCP broadcast packets. A remote attacker can exploit this, via a specially crafted packet, to cause a denial of service condition.
(CVE-2017-6865)

- A denial of service vulnerability exists in the DCOM interface due to improper handling of specially crafted messages. An authenticated, remote attacker who is a member of the 'administrators' group can exploit this, via a specially crafted message, to cause a denial of service condition. (CVE-2017-6867)

Solution

Upgrade to Siemens SIMATIC WinCC (TIA Portal) version 13 SP2 (1300.200.1001.1) / 14 SP1 (1400.100.1201.1) or later..
