英文原文描述

NetComm NF20MESH routers running firmware R6B031 and earlier contain an authentication bypass vulnerability that allows unauthenticated attackers to gain administrative access by exploiting a hardcoded AES-256 key used to encrypt session cookies for the web management interface. Attackers can forge a valid encrypted session cookie using the shared hardcoded key and bypass authentication checks to obtain full administrative control of the management interface while any legitimate administrator session is active.
