MQTT credentials and control traffic are transmitted in cleartext, exposing sensitive information to network-level attackers. This may enable unauthorized device impersonation and disruption of messaging functions.

The affected Ebyte device web management interface does not restrict the interface from being rendered within an external frame. An unauthenticated remote attacker could use a crafted webpage to mislead an authenticated administrator into initiating unintended configuration changes or disruptive actions.

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

product's vendor configuration utility permits access to administrative functions without verifying the operator's identity under certain credential conditions. An unauthenticated attacker on the adjacent network could modify critical settings or change access credentials, potentially preventing legitimate administrators from managing the device.

The affected Ebyte

product exports administrative credentials and other sensitive configuration information without adequate protection. An unauthenticated attacker on the adjacent network who can obtain an exported configuration file could recover valid credentials and use them to access the device or similarly configured systems.

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.

The affected Ebyte

product uses a deprecated hashing algorithm in an authentication-related operation. Under conditions where an attacker can manipulate or predict the authentication exchange, the weak construction may reduce the assurance provided by the authentication mechanism and facilitate unauthorized access.
