high Nessus Plugin ID 82853

Synopsis

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

Description

The version of Siemens SIMATIC WinCC (TIA Portal) installed on the remote host is 13.x prior to version 13 service pack 1 update 2 (1300.102.401.5). It is, therefore, affected by multiple vulnerabilities :

- A man-in-the-middle attacker with access to the network path between an HMI panel and a PLC can conduct a denial of service attack against the HMI panel by sending specially crafted packets to the HMI on TCP port 102.
This vulnerability affects SIMATIC WinCC Comfort Panels and SIMATIC WinCC Runtime Advanced. (CVE-2015-2822)

- A remote attacker, by obtaining password hashes for SIMATIC WinCC users, can use the hashes to successfully authenticate as a valid user. (CVE-2015-2823)

Solution

Upgrade to Siemens SIMATIC WinCC (TIA Portal) version 13 SP1 Upd2 (1300.102.401.5) or later.
