An improper protection of authentication tokens vulnerability exists in certain Ebyte gateway products. Authentication tokens used by the web management interface are insufficiently protected during client-side session handling, which may allow an attacker with access to exposed 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.
