Description

A vulnerability in SenseLive X3050’s web management interface allows authentication logic to be performed entirely on the client side, relying on hardcoded values within browser-executed scripts rather than server-side verification. An attacker with access to the login page could retrieve these exposed parameters and gain unauthorized access to administrative functionality.
