wan.htm page on Zyxel NBG-418N v2 with firmware version V1.00(AARP.9)C0 can be accessed directly without authentication, which can lead to disclosure of information about the WAN, and can also be leveraged by an attacker to modify data fields of the page.
The product does not perform any authentication for functionality that requires a provable user identity or consumes a significant amount of resources.
