CVE-2026-73839

The Ebyte device web management interface does not consistently enforce authentication before granting access to administrative functionality. An unauthenticated remote attacker could access sensitive configuration information, modify device settings, or disrupt availability.

The Ebyte device relies on client side authentication logic that can be reproduced by unauthenticated users. An attacker may generate valid authentication requests and bypass authentication to obtain administrative access to the device.

The affected Ebyte device relies on client-managed authentication tokens without sufficient server-side validation. An attacker may replay or manipulate authentication tokens to gain unauthorized access to administrative functionality.

The affected Ebyte device does not restrict repeated authentication attempts through rate limiting or account lockout mechanisms. This could allow an attacker to perform automated authentication attacks against deployments that rely on password based authentication.

The Ebyte device does not adequately verify the origin or authenticity of requests submitted to the web management interface. An unauthenticated remote attacker could persuade an authenticated administrator to visit a crafted page, causing unauthorized configuration changes or a disruption of device availability.

Certain configuration endpoints may lack proper server-side authorization checks, allowing unauthorized users to access or modify sensitive device settings. This could result in full compromise of device functionality.

The Ebyte device web management interface does not restrict rendering within an external frame (clickjacking). An unauthenticated remote attacker could use a crafted webpage to mislead an authenticated administrator into unintended configuration changes or disruptive actions.
