CVE-2025-41768 1 Beckhoff 1 Twincat 2026-02-12 5.5 Medium
An high privileged remote attacker can inject arbitrary content into the custom CSS field on the affected devices due to improper neutralization of input during web page generation ('Cross-site Scripting').
CVE-2025-41727 1 Beckhoff 4 Beckhoff.device.manager.xar, Mdp Package, Twincat and 1 more 2026-01-27 7.8 High
A local low privileged attacker can bypass the authentication of the Device Manager user interface, allowing them to perform privileged operations and gain administrator access.
CVE-2025-41726 1 Beckhoff 4 Beckhoff.device.manager.xar, Mdp Package, Twincat and 1 more 2026-01-27 8.8 High
A low privileged remote attacker can execute arbitrary code by sending specially crafted calls to the web service of the Device Manager or locally via an API and can cause integer overflows which then may lead to arbitrary code execution within privileged processes.
CVE-2025-41728 1 Beckhoff 4 Beckhoff.device.manager.xar, Mdp Package, Twincat and 1 more 2026-01-27 5.3 Medium
A low privileged remote attacker may be able to disclose confidential information from the memory of a privileged process by sending specially crafted calls to the Device Manager web service that cause an out-of-bounds read operation under certain circumstances due to ASLR and thereby potentially copy confidential information into a response.
CVE-2014-5415 1 Beckhoff 2 Embedded Pc Images, Twincat 2025-11-05 9.1 Critical
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.
CVE-2014-5414 1 Beckhoff 2 Embedded Pc Images, Twincat 2025-11-05 9.1 Critical
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.
CVE-2025-41701 1 Beckhoff 1 Twincat 2025-09-10 7.8 High
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.
CVE-2011-3486 1 Beckhoff 1 Twincat 2025-04-11 N/A
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.
CVE-2020-12494 2 Beckhoff, Intel 20 Twincat, Twincat Driver, 82540em and 17 more 2024-11-21 5.3 Medium
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.
CVE-2019-5637 1 Beckhoff 3 Twincat, Twincat Cx2030, Twincat Cx5140 2024-11-21 7.5 High
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).
CVE-2019-5636 1 Beckhoff 1 Twincat 2024-11-21 5.3 Medium
When a Beckhoff TwinCAT Runtime receives a malformed UDP packet, the ADS Discovery Service shuts down. Note that the TwinCAT devices are still performing as normal. This issue affects TwinCAT 2 version 2304 (and prior) and TwinCAT 3.1 version 4204.0 (and prior).
CVE-2019-16871 1 Beckhoff 1 Twincat 2024-11-21 9.8 Critical
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.
CVE-2018-7502 1 Beckhoff 2 Twincat, Twincat C\+\+ 2024-11-21 N/A
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.
CVE-2017-16726 1 Beckhoff 1 Twincat 2024-11-21 N/A
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.
CVE-2017-16718 1 Beckhoff 1 Twincat 2024-11-21 N/A
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.
