Original NVD Description

Huawei HG630 V2 router contains an authentication bypass vulnerability that allows unauthenticated attackers to obtain administrative access by retrieving the device serial number. Attackers can query the /api/system/deviceinfo endpoint without authentication to extract the SerialNumber field, then use the last 8 characters as the default password to log in to the router.
