CVSS: 5.3EPSS: 0%CPEs: 63EXPL: 0CVE-2020-12494 – Beckhoff: Etherleak in TwinCAT RT network driver
https://notcve.org/view.php?id=CVE-2020-12494
16 Jun 2020 — 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. • https://cert.vde.com/en-us/advisories/vde-2020-019 • CWE-459: Incomplete Cleanup •

27 Jun 2018 — 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.
