Technical details
The vulnerability is an improper protection of authentication tokens (CWE-613) in the web management interface of the Ebyte NE2-D11 gateway. Authentication tokens used for client-side session handling are insufficiently protected, allowing an attacker with access to network traffic or session information to capture and replay valid tokens. The flaw is part of a broader authentication weakness (related to CWE-306: Missing Authentication for Critical Function) that also involves client-side authentication logic. An attacker with network access can intercept tokens and impersonate an authenticated administrator. No patch has been released; the vendor acknowledged the issue but has not provided remediation guidance.
