Summary

A cleartext transmission of sensitive information vulnerability exists in certain Ebyte gateway products.

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.
