Reino: Input Validation and Representation

Problemas de validação e representação da entrada são causados por metacaracteres, codificações alternativas e representações numéricas. Confiar na entrada resulta em problemas de segurança. Os problemas incluem: “Buffer Overflows”, ataques de “Cross-Site Scripting”, “SQL Injection”, entre outros.

Missing Form Field Validation

Java/JSP
Scala

Abstract

O aplicativo não executa nenhuma validação para os dados do formulário.

Explanation

O aplicativo falha ao validar o tipo de dados recebidos de um formulário da web. É uma boa prática validar se os dados recebidos satisfazem as exigências definidas para os dados esperados.

Exemplo 1: O código a seguir define um Spring WebFlow FormAction que não consegue validar os dados em relação às exigências esperadas:


    <bean id="customerCriteriaAction" class="org.springframework.webflow.action.FormAction">
        <property name="formObjectClass"
            value="com.acme.domain.CustomerCriteria" />
        <property name="propertyEditorRegistrar">
            <bean
                class="com.acme.web.PropertyEditors" />
        </property>
    </bean>

Exemplo 2: O código a seguir define o estado de uma ação do Spring WebFlow que não consegue validar os dados em relação às exigências esperadas:


    <action-state>
        <action bean="transferMoneyAction" method="bind" />
    </action-state>

Abstract

O aplicativo não realiza nenhuma validação dos dados do formulário.

Explanation

O aplicativo não consegue validar o tipo de dados recebido de um formulário da Web. É uma prática recomendada validar que os dados recebidos satisfazem os requisitos definidos para os dados esperados.

Exemplo 1: O seguinte código define um formulário, mas não consegue validar os dados em relação aos requisitos esperados:


  def form = Form(
    mapping(
      "name" -> text,
      "age" -> number
    )(UserData.apply)(UserData.unapply)
  )
