Local attackers can cause affected CODESYS Development System V2.3 installations to crash or execute code by opening malicious project files.

The CODESYS Development System V2.3 is an IEC 61131-3 programming tool for the industrial controller and automation technology sector. It stores the program code for the controller and its configuration in project files (*.pro).

Welotec has been informed by an external source that the WebUI of the device management solution "SMART EMS" and the remote connectivity solution "VPN Security Suite" is vulnerable to so-called "Clickjacking" and advises to update to version v3.1.4 or later.

Critical vulnerabilities have been discovered in the product due to outdated software components.
The impact of the vulnerabilities on the affected device may result in

• Denial of service
• Bypassing of authentication
• Information disclosure

Welotec has closed two vulnerabilities in the TK500v1 router series and advises to update the routers to firmware version r5542 or later. An exploitation of the vulnerabilities can allow an attacker to manipulate the device.

The Web-Based Management (WBM) of WAGOs programmable logic controller (PLC) is typically used for administration, commissioning, and updates.

The option to change the configuration data via tools or the web-based-management enabled attackers to prepare cross-site-scripting attacks and under specific circumstances perform remote code execution.

Multiple Wiesemann & Theis software products are affected by a vulnerability through an unquoted search path in the Windows registry. A local attacker can execute arbitrary code and gain administrative privileges by inserting an executable file in the path of the affected product.

Update A, 07.03.2024

Incorrect version numbers have been corrected.

MES PCs shipped with Windows 10 come pre-installed with XAMPP. XAMPP is a bundle of third-party open-source applications including the Apache HTTP Server, the MariaDB database and more. From time to time, vulnerabilities in these applications are discovered. These are fixed in newer versions of XAMPP by updating the bundled applications.

MES PCs shipped with Windows 10 include a copy of XAMPP which contains around 140 such vulnerabilities listed in this advisory. They can be fixed by replacing XAMPP with Festo Didactic's Factory Control Panel application.

The vulnerabilities covered by this advisory have a broad range of impacts ranging from denial-ofservice to disclosure or manipulation/deletion of information. Given the intended usage of MES PCs for didactic purposes in controlled lab environments, separate from productive systems, it never comes into contact with sensitive information. Therefore the impact is reduced to limited availability of the system.

Overall, the product is affected by the following CVEs:
