CVE-2022-50978Network attack vector

Operational disruption via unauthenticated Modbus preset switching

Published Feb 2, 2026 · Updated Feb 2, 2026

Missing authentication in affected VLX and AVLX firmware allows remote attackers to disrupt operations through Modbus/TCP preset switching. The preset-switch function accepts Modbus/TCP requests without authenticating the sender and applies the selected configuration. Network access and multiple stored presets are required; exploitation changes the active preset and interrupts normal operation.
