CVE-2026-27843Network attack vector

Persistent lockout via unauthenticated configuration changes

Published Apr 23, 2026 · Updated Apr 24, 2026

Missing authentication in the SenseLive Technologies X3050 1.523 web interface allows remote attackers to cause persistent device lockout. The interface accepts unsupported values for recovery and network settings without sufficient authentication or server-side validation. Network access to the management interface is sufficient; recovery requires specialized console access for a factory reset, interrupting the gateway and its connected RS-485 systems.
