Description
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.
