Recommended response

  1. 1Check inventory. Check lockfiles and deployed manifests for Ebyte/Ebyte NA111-M Firmware, Ebyte/Ebyte NE2-D11 Firmware.
  2. 2Review the reported fix. Source-reported workaround: 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.

Sources and claim methodology

  • GitHub security advisorygithub.com
  • CISA Known Exploited Vulnerabilities catalogcisa.gov
Upstream source description

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.
