Reino: API Abuse

Uma API é um contrato entre quem chama e o que se chama. As formas mais comuns de abuso de API ocorrem quando o responsável pela chamada não respeita sua parte do contrato. Por exemplo, se um programa não chama chdir() após chamar chroot(), ele viola o contrato que especifica como alterar o diretório raiz ativo de forma segura. Outro bom exemplo de abuso de biblioteca é esperar que o elemento chamado retorne informações confiáveis de DNS ao responsável pela chamada. Nesse caso, o responsável pela chamada abusa a API do elemento chamado ao fazer certas suposições sobre seu comportamento (isto é, que o valor de retorno pode ser usado para fins de autenticação). A outra parte também pode violar o contrato entre quem chama e o que se chama. Por exemplo, se um programador definir SecureRandom como subclasse e retornar um valor não aleatório, o contrato será violado.

Often Misused: Spring Web Service

Java/JSP

Abstract

Os serviços da web são configurados no aplicativo Spring. Por padrão, esses serviços da web não requerem autenticação e as informações transferidas deste serviço e para ele estão em texto simples. Isso pode permitir que um invasor acesse operações com privilégios ou exponha dados confidenciais.

Explanation

O Spring fornece um mecanismo fácil para transformar qualquer bean gerenciado pelo Spring em serviços da web por meio do Spring WS ou XFire. Qualquer método público do bean Spring remoto pode ser chamado externamente e os dados que estão sendo passados entre o cliente e os objetos habilitados pelo serviço da web estão em texto simples. O maior problema com esses serviços é que eles são abertos por padrão e não oferecem garantias de confidencialidade ou integridade por padrão.
