CVE-2021-32030 is an improper authentication vulnerability in the administrator application of ASUS GT-AC2900 devices before 3.0.0.4.386.42643 and Lyra Mini devices before 3.0.0.4_384_46630; unsupported end-of-life Lyra Mini versions are also affected. The flaw allows an unauthenticated remote user to bypass authentication and gain access to the administrator interface. The issue is associated with request handling in handle_request within router/httpd/httpd.c and authentication logic in auth_check in web_hook.o. According to the provided content, authentication can succeed when an attacker-supplied token value of '\0' matches the device's default '\0' value under certain conditions, resulting in acceptance of unauthenticated input as valid administrator authentication.
