Technical description

An improper protection of authentication tokens vulnerability exists in

certain Ebyte gateway products. Authentication tokens used by the web

session information to obtain and reuse a valid token. Successful

exploitation could allow an attacker to impersonate an authenticated

user and gain unauthorized access to device management functionality.
