CVE-2023-29680Public exploit

Password disclosure via cleartext ecos_pw cookie

Published May 1, 2023 · Updated Jan 30, 2025

Cleartext transmission in Tenda N301 v6.0 firmware 12.02.01.61_multi allows remote authenticated users to capture the router password. The web management interface places the ecos_pw credential in a cleartext Set-Cookie response header, exposing it to traffic interception. Access requires authentication and LAN or WLAN position; the documented consequence is password disclosure, not configuration change or service interruption.
