Authentication bypass in Chunghwa Telecom Nokia G-040W-Q G040WQR201207 allows remote attackers to gain an existing user's access via a crafted URL. The web management interface treats requests to an undisclosed alternative URL as authenticated without validating credentials. No credentials or user interaction are required; administrator impersonation permits arbitrary system commands, device control, and service interruption.
