Official Description

A vulnerability exists in SenseLive X3050's web management interface that allows critical configuration parameters to be modified without sufficient authentication or server-side validation. By applying unsupported or disruptive values to recovery mechanisms and network settings, an attacker can induce a persistent lockout state. Because the device lacks a physical reset button, recovery requires specialized technical access via the console to perform a factory reset, resulting in a total denial-of-service for the gateway and its connected RS-485 downstream systems.

Technical Analysis

CVE-2026-27843 can be exploited remotely over the network without requiring physical or adjacent access, significantly expanding the attack surface for threat actors.

The vulnerability requires no privileges and no user interaction, making it a prime target for automated exploitation campaigns and worm-like propagation.

A successful exploit results in full integrity compromise (data manipulation), availability disruption (denial of service), with a CVSS base score of 9.1.
