LINK-NET LW-N605R devices with firmware 12.20.2.1486 allow Remote Code Execution via shell metacharacters in the HOST field of the ping feature at adm/systools.asp. Authentication is needed but the default password of admin for the admin account may be used in some cases.
The product initializes or sets a resource with a default that is intended to be changed by the administrator, but the default is not secure.

Developers often choose default values that leave the product as open and easy to use as possible out-of-the-box, under the assumption that the administrator can (or should) change the default value. However, this ease-of-use comes at a cost when the default is insecure and the administrator does not change it.
