Description
U-SPEED N300 router V1.0.0 does not implement rate limiting or account lockout protections on the /api/login endpoint. This allows an attacker on the local network to perform unlimited authentication attempts, enabling brute-force attacks against the administrator account and potential unauthorized access to the router management interface.
Affected products
