The Voo branded NETGEAR CG3700b custom firmware V2.02.03 uses the same default 8 character passphrase for the administrative console and the WPA2 pre-shared key. Either an attack against HTTP Basic Authentication or an attack against WPA2 could be used to determine this passphrase.

Weakness

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.

Affected Software

Name Vendor Start Version End Version
Cg3700b_firmware Netgear 2.02.03 (including) 2.02.03 (including)

Extended Description

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.
