Ebyte NE2-D11 Vulnerabilities Exposed

Published on: August 25, 2026

Successful exploitation of these vulnerabilities could allow an attacker to gain unauthorized administrative access, disclose sensitive information, modify device configuration, hijack authenticated sessions, and disrupt device operation. The following versions of Ebyte NE2-D11 are affected: NE2-D11 Firmware FW-9167-0-11. These devices are deployed worldwide, specifically within Critical Infrastructure Sectors such as Critical Manufacturing and Energy. 🚀

Identified Vulnerabilities

Among the identified vulnerabilities is CVE-2026-73125, where the Ebyte device web management interface does not consistently enforce authentication before granting access to administrative functionality. An unauthenticated remote attacker could access sensitive configuration information, modify device settings, or disrupt availability. Additionally, CVE-2026-73809 details a cleartext transmission of sensitive information vulnerability 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. 🔒

Further vulnerabilities include CVE-2026-73839, which states that administrative credentials may be exposed in plaintext within the Ebyte device’s management interface, increasing the risk of credential compromise through visual or remote observation. CVE-2026-71187 notes that the Ebyte device relies on client-side authentication logic that can be reproduced by unauthenticated users. An attacker may generate valid authentication requests and bypass authentication to obtain administrative access to the device. Moreover, CVE-2026-76179 describes an improper protection of authentication tokens vulnerability where authentication tokens used by the web management interface are insufficiently protected during client-side session handling. Successful exploitation could allow an attacker to impersonate an authenticated user and gain unauthorized access to device management functionality. CVE-2026-75813 highlights that certain configuration endpoints may lack proper server-side authorization checks, allowing unauthorized users to access or modify sensitive device settings. This could result in full compromise of device functionality. Lastly, CVE-2026-69658 indicates that MQTT credentials and control traffic are transmitted in cleartext, exposing sensitive information to network-level attackers. ⚠️

Remediation

Regarding remediation, Ebyte acknowledged receipt of the reported vulnerabilities and indicated that a patch was under development. However, the vendor has not responded to subsequent requests for coordination, and CISA has not been informed of the status or availability of the patch. Users are encouraged to reach out to Ebyte for more information. Jithin Nambiar reported these vulnerabilities to CISA. CISA recommends users take defensive measures to minimize the risk of exploitation.
