| CVE-2020-12494 | 2 Beckhoff, Intel | 20 Twincat, Twincat Driver, 82540em and 17 more | 2021-12-02 | 5.0 MEDIUM | 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-2021-34594 | 1 Beckhoff | 4 Tf6100, Tf6100 Firmware, Ts6100 and 1 more | 2021-11-06 | 8.5 HIGH | 6.5 MEDIUM |
| 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. | |||||
| CVE-2020-12526 | 1 Beckhoff | 3 Ipc Diagnostics Ua Server, Tf6100, Twincat Opc Ua Server | 2021-05-25 | 5.0 MEDIUM | 5.3 MEDIUM |
| 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. | |||||
| CVE-2017-16718 | 1 Beckhoff | 1 Twincat | 2019-10-09 | 4.3 MEDIUM | 5.9 MEDIUM |
| 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. | |||||
