What is CVE-2023-42770?

An authentication bypass vulnerability exists in Red Lion SixTRAK and VersaTRAK Series RTUs when messages are processed over TCP/IP. Specifically, while these devices enforce an authentication challenge for UDP/IP messages, they fail to do so when receiving the same messages via TCP/IP. This design oversight allows unauthenticated users to send commands to the RTUs, potentially compromising the integrity and security of the systems relying on these devices.
