Kernel drivers in Beckhoff TwinCAT 3.1 Build 4022.4, TwinCAT 2.11 R3 2259, and TwinCAT 3.1 lack proper validation of user-supplied pointer values. An attacker who is able to execute code on the target may be able to exploit this vulnerability to obtain SYSTEM privileges.8.5CVE-2021-34594beckhoff automationtwincat opc ua server+2

TwinCAT OPC UA Server in TF6100 and TS6100 in product versions before 4.3.48.0 or with TcOpcUaServer versions below 3.2.0.194 are prone to a relative path traversal that allow administrators to create or delete any files on the system.9CVE-2015-4051beckhoffipc_diagnostics

Beckhoff IPC Diagnostics before 1.8 does not properly restrict access to functions in /config, which allows remote attackers to cause a denial of service (reboot or shutdown), create arbitrary users, or possibly have unspecified other impact via a crafted request, as demonstrated by a beckhoff.com:service:cxconfig:1#Write SOAP action to /upnpisapi.7.8CVE-2025-41701beckhoffte1000 | twincat 3 enineering

An unauthenticated attacker can trick a local user into executing arbitrary commands by opening a deliberately manipulated project file with an affected engineering tool. These arbitrary commands are executed in the user context.9.8CVE-2020-20741beckhoffcx9020

Incorrect Access Control in Beckhoff Automation GmbH & Co. KG CX9020 with firmware version CX9020_CB3011_WEC7_HPS_v602_TC31_B4016.6 allows remote attackers to bypass authentication via the "CE Remote Display Tool" as it does not close the incoming connection on the Windows CE side if the credentials are incorrect.5.3CVE-2020-12526beckhoffipc_diagnostics_ua_server+2
EPSS score
0.95%
TwinCAT OPC UA Server in versions up to 2.3.0.12 and IPC Diagnostics UA Server in versions up to 3.1.0.1 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.5.3CVE-2020-12494beckhofftwincat+3
EPSS score

Beckhoff's TwinCAT RT network driver for Intel 8254x and 8255x is providing EtherCAT functionality. The driver implements real-time features. Except for Ethernet frames sent from real-time functionality, all other Ethernet frames sent through the driver are not padded if their payload is less than the minimum Ethernet frame size. Instead, arbitrary memory content is transmitted within in the padding bytes of the frame. Most likely this memory contains slices from previously transmitted or received frames. By this method, memory content is disclosed, however, an attacker can hardly control which memory content is affected. For example, the disclosure can be provoked with small sized ICMP echo requests sent to the device.7.3CVE-2020-12510beckhofftwincat_extended_automation_runtime+1

The default installation path of the TwinCAT XAR 3.1 software in all versions is underneath C:\TwinCAT. If the directory does not exist it and further subdirectories are created with permissions which allow every local user to modify the content. The default installation registers TcSysUI.exe for automatic execution upon log in of a user. If a less privileged user has a local account he or she can replace TcSysUI.exe. It will be executed automatically by another user during login. This is also true for users with administrative access. Consequently, a less privileged user can trick a higher privileged user into executing code he or she modified this way. By default Beckhoff’s IPCs are shipped with TwinCAT software installed this way and with just a single local user configured. Thus the vulnerability exists if further less privileged users have been added.9.4CVE-2014-5415beckhoffembedded_pc_images+2

Beckhoff Embedded PC images before 2014-10-22 and Automation Device Specification (ADS) TwinCAT components might allow remote attackers to obtain access via the (1) Windows CE Remote Configuration Tool, (2) CE Remote Display service, or (3) TELNET service.9.4CVE-2014-5414beckhoffembedded_pc_images+2
EPSS score
4.80%
Beckhoff Embedded PC images before 2014-10-22 and Automation Device Specification (ADS) TwinCAT components do not restrict the number of authentication attempts, which makes it easier for remote attackers to obtain access via a brute-force attack.5CVE-2011-3486beckhofftwincat
EPSS score

Beckhoff TwinCAT 2.11.0.2004 and earlier allows remote attackers to cause a denial of service via a crafted request to UDP port 48899, which triggers an out-of-bounds read.5.9CVE-2017-16718beckhofftwincat+1

Beckhoff TwinCAT 3 supports communication over ADS. ADS is a protocol for industrial automation in protected environments. This protocol uses user configured routes, that can be edited remotely via ADS. This special command supports encrypted authentication with username/password. The encryption uses a fixed key, that could be extracted by an attacker. Precondition of the exploitation of this weakness is network access at the moment a route is added.9.1CVE-2017-16726beckhofftwincat+1
EPSS score
0.51%
Beckhoff TwinCAT supports communication over ADS. ADS is a protocol for industrial automation in protected environments. ADS has not been designed to achieve security purposes and therefore does not include any encryption algorithms because of their negative effect on performance and throughput. An attacker can forge arbitrary ADS packets when legitimate ADS traffic is observable.7.3CVE-2024-41176beckhoffmdp_package+1

The MPD package included in TwinCAT/BSD allows an authenticated, low-privileged local attacker to induce a Denial-of-Service (DoS) condition on the daemon and execute code in the context of user “root” via a crafted HTTP request.7.3CVE-2024-41174beckhoffipc_diagnostics_package+1

A local user with administrative access rights can enter specialy crafted values for settings at the user interface (UI) of the TwinCAT Package Manager which then causes arbitrary OS commands to be executed.9.8CVE-2019-16871beckhofftwincat

Beckhoff Embedded Windows PLCs through 3.1.4024.0, and Beckhoff Twincat on Windows Engineering stations, allow an attacker to achieve Remote Code Execution (as SYSTEM) via the Beckhoff ADS protocol.7.5CVE-2019-5637beckhofftwincat+2
EPSS score

When Beckhoff TwinCAT is configured to use the Profinet driver, a denial of service of the controller could be reached by sending a malformed UDP packet to the device. This issue affects TwinCAT 2 version 2304 (and prior) and TwinCAT 3.1 version 4204.0 (and prior).
