3S CODESYS Runtime 3.x < 3.5.14.20 Multiple Vulnerabilities

critical Nessus Plugin ID 134977
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

A programmable logic controller (PLC) runtime on the remote host is affected by multiple vulnerabilities.

Description

The 3S CODESYS Runtime environment running on the remote host is affected by multiple vulnerabilities:

- The CODESYS Gateway does not correctly verify the ownership of a communication channel. (CVE-2019-9010)

- A crafted communication request may cause uncontrolled memory allocations in the affected CODESYS products and may result in a denial-of-service condition. (CVE-2019-9012)

- The application may utilize non-TLS based encryption, which results in user credentials being insufficiently protected during transport. (CVE-2019-9013)

Note that Nessus has not tested for the issue but has instead relied only on the application's self-reported version number.

Solution

Upgrade 3S CODESYS Runtime to version 3.5.14.20 or higher.
