Risk evaluation

A number of TRUMPF software tools use the OPC UA Server in C++ based OPC UA SDK by Unified Automation. The application contains several vulnerabilities, which enable an attacker to send malicious data to the application, resulting in a Denial-of-Service.

Mitigatiesamenvatting

Use the updated versions of the TRUMPF OPC UA server that will be available via MyTRUMPF.

Risk evaluation

The machine controller of the cabinet series include an OPC-UA server which uses an user management to authenticate clients via anonymous or user/password authentication. If the user/password authentication is selected, password verification is skipped upon second login. As a result, cases occur in which users can establish communication without correct authentication. This vulnerability is not located in the OPC-UA protocol or server, but in the interface to the products firmware. This Security Advisory is only relevant for the following use cases: • the user management has been activated on the machine controller (is deactivated by default) • the OPC-UA Server is used • Data are transferred via a symbol configuration (is not available by default)

Mitigatiesamenvatting

As part of a security strategy, Lenze SE recommends the following general defense measures to reduce the risk of exploits: • Only use the products in a protected and controlled environment to minimize network impact and to ensure that they are inaccessible from outside. • Use external firewalls to protect the automation system network and to separate it from other networks. Remark: One Measure should be to block port 4840 via the external firewall and open this port for authenticated access only. • Use Virtual Private Networks (VPN) tunnels when remote access is required. • Use IDS (Intrusion Detection Systems) where possible to detect anomalies in the network. • Activate and use user administration and password functions. • Use encrypted communication links. • Restrict access to both the development tools and their projects and the products of the automation system by physical means, operating system functions, etc. • Protect the development tool by using the latest virus detection solutions. • Use of certificate-based communication via the message security modes Sign or Sign&Encrypt and trust of the corresponding client certificates on the machine controller by the OPC-UA server. This can reduce the risk of exploiting this vulnerability.

The affected products contain a CODESYS Control runtime system in version V2. They are therefore affected by the vulnerability described in CODESYS Advisory 2021-06. It provides a communication server for the communication with clients like the CODESYS Development System. The 9400 servo inverters is only affected if the communication Path via the inserted EtherNet Module E94AYCEN on slot MXI1 or MXI2 is used. If the Module E94AYCEN is used, the following Versions are affected. Product Identification: E94xSHxxx (Single Drive, High Line) Product Identification: E94xMHxxx (Multi Drive, High Line) Remark: If the product identification of your 9400 product does not fit to the above mentioned identification, please contact Lenze at Security.de@Lenze.com. The Versions P (power supply module) and R (regenerative power supply module) are not affected. Furthermore, the Variant P (PLC) and the Variant S (StateLine) are not affected. The communication paths via the diagnostic interface X6, the system bus (CAN) X1 or the field buses (other than the named Ethernet module) that can be plugged into the module slots MXI1 or MXI2 are not affected. The focus is therefore on 9400 servo inverters with the product-identification E94x{S/M}{H}... with a plugged in Ethernet module E94AYCEN... in module slot MXI1 or MXI2 and communication with the Engineer-Tools via exactly this channel. In addition to the standard tool Engineer, there is also a special Version of the PLC Designer (Version 0.x). The communication path to the PLC Designer is not considered with the planned update and the vulnerabilities here remain even after the update. Here, the customer must provide a secure Environment, see Mitigation.

Some TwinCAT OPC UA Server and IPC Diagnostics UA Server versions from Beckhoff Automation GmbH & Co. KG are vulnerable to denial of service attacks. The attacker needs to send several specifically crafted requests to the running OPC UA server. After some of these requests the OPC UA server is no longer responsive to any client. This is without effect to the real-time functionality of IPCs. UPDATE A - 11.05.2021 Please note that some hardware products from Beckhoff are shipped with a TwinCAT OPC UA Server pre-installed. In some cases the server is enabled by default. IPC Diagnostics UA Server (contained in Beckhoff's Windows images) server versions up to and including 3.1.0.1 are affected Please note that IPC products from Beckhoff are shipped with an IPC Diagnostics UA Server pre-installed. In all cases the server is disabled by default. The version numbers named above always refer to the version number which is accessible via OPC UA at the server via the standard OPC UA node /Objects/Server/ServerStatus/BuildInfo/SoftwareVersion and on Windows also as the file property "File version" of the file TcOpcUaServer.exe for TwinCAT OPC UA Server respectively the file DevMgrSvr-UA.exe for IPC Diagnostics UA Server. UPDATE A - 11.05.2021 Please note that IPC products from Beckhoff are shipped with an IPC Diagnostics UA Server pre-installed. While on Windows CE it is disabled by default all other Windows images have it enabled by default.

Mitigatiesamenvatting

Consider disabling the IPC Diagnostics Server by stopping and disabling the corresponding Windows service or service. For example this can be achieved with the following PowerShell commands: Stop-Service -Force -Name DevMgrSvr-UA Set-Service -Name DevMgrSvr-UA -StartupType Disabled Alternatively consider limiting access to the TCP port the OPC UA server is listening on. This can happen with a dedicated firewall appliance which sits in front of an affected device. Alternatively at the device the Windows firewall can be configured to limit access to the TCP port. Further guidance is provided within the "Security Guide IPC" from Beckhoff which is accessible at https://www.beckhoff.com/secguide
