high Nessus Plugin ID 125392
New! Plugin Severity Now Using CVSS v3

The calculated severity for Plugins has been updated to use CVSS v3 by default. Plugins that do not have a CVSS v3 score will fall back to CVSS v2 for calculating severity. Severity display preferences can be toggled in the settings dropdown.

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 Windows host is prior to version 15 update 4.
It is, therefore, affected by the following vulnerabilities:

- An unspecified directory traversal vulnerability exists. An unauthenticated, remote attacker can exploit this, by sending a URI that contains directory traversal characters, to disclose the contents of files located outside of the server's restricted path. (CVE-2018-13812)

- An URL redirection vulnerability exists in the webserver of HMI devices. A remote attacker can exploit this by tricking a user into visiting a specially crafted web page, allowing the attacker to disclose sensitive information. (CVE-2018-13813)

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 15 update 4 or later.
