CVE-2026-73839

Credential disclosure via plaintext management interface

Published Aug 27, 2026 · Updated Aug 27, 2026

Insufficiently protected credentials in Ebyte NE2-D11 Firmware FW-9167-0-11 allow physically proximate attackers to read admin credentials. The management interface presents administrative credentials as plaintext; CISA does not identify the page, field, or code path responsible. The scored path requires physical access to view the interface, and successful observation discloses device-administration credentials without altering device data or availability.
