What is CVE-2021-20149?

The Trendnet AC2600 TEW-827DRU router version 2.08B01 is subject to a vulnerability that permits unrestricted access to its services over the WAN interface. This issue arises from inadequate access control mechanisms, as the default iptables rules apply only to IPv4 traffic. Consequently, services running on this device are exposed via IPv6 by default, posing a substantial security risk to users.
