Vulnerabilidades de Ebyte

The affected Ebyte product does not provide separation between limited and administrative management functions. A low privileged authenticated attacker could access security sensitive configuration functions and modify settings that affect the confidentiality, integrity, or availability of the device.

Ebyte gateway product's vendor configuration utility does not require authentication before allowing certain disruptive administrative actions when default credentials remain configured. An unauthenticated attacker on the adjacent network could reboot the device or restore factory settings, resulting in a loss of configuration and service availability.

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.

A cleartext transmission of sensitive information vulnerability exists in certain Ebyte gateway products. The web management interface does not adequately protect sensitive communications using transport-layer encryption. An attacker with access to network traffic could intercept authentication or session-related information transmitted between a user and the affected device. Successful exploitation could result in disclosure of sensitive information and unauthorized access to device management functionality.
