CVE-2026-27843 Details
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.
A vulnerability in the web management interface of the SenseLive X3050 gateway allows critical configuration parameters to be altered without proper authentication or server-side validation. This issue can be exploited by applying unsupported or disruptive values to recovery mechanisms and network settings, leading to a persistent lockout state. The device does not have a physical reset button, so recovery requires specialized technical access via the console to perform a factory reset. This situation causes a total denial-of-service for the gateway and its connected RS-485 downstream systems.
SenseLive did not respond to CISA's requests to coordinate. Affected users are encouraged to reach out to SenseLive for more information.
