CVE-2026-77975

Ebyte NA111-M Cleartext Storage of Sensitive Information

The affected Ebyte product exports administrative credentials and other sensitive configuration information without adequate protection. An unauthenticated attacker on the adjacent network who can obtain an exported configuration file could recover valid credentials and use them to access the device or similarly configured systems.

CVE-2026-76179

Ebyte NA111-M Use of GET Request Method With Sensitive Query Strings

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.

CVE-2026-73809

Ebyte NA111-M Cleartext Transmission of Sensitive Information

A cleartext transmission of sensitive information vulnerability exists in certain Ebyte gateway products. The web management interface does not adequately protect sensitive communications using transport-layer encryption. 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.
