CVE-2020-12494 2 Beckhoff, Intel 20 Twincat, Twincat Driver, 82540em and 17 more 2021-12-02 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-2019-16871 1 Beckhoff 1 Twincat 2021-07-21 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-2019-5637 1 Beckhoff 3 Twincat, Twincat Cx2030, Twincat Cx5140 2020-02-04 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 2020-02-04 7.5 High
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-2017-16726 1 Beckhoff 1 Twincat 2019-10-09 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 2019-10-09 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.
CVE-2018-7502 1 Beckhoff 2 Twincat, Twincat C\+\+ 2018-05-23 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-2011-3486 1 Beckhoff 1 Twincat 2017-08-29 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-2014-5415 1 Beckhoff 2 Embedded Pc Images, Twincat 2016-11-28 N/A
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 2016-11-28 N/A
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.
