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.

Struts: Validator Turned Off

Java/JSP

Abstract

Este mapeamento de formulário de ação desativa o método validate() do formulário.

Explanation

Um mapeamento de formulário de ação nunca deve desabilitar a validação. Desativar a validação desativa o Validador Struts, bem como qualquer lógica de validação personalizada realizada pelo formulário.

Exemplo 1: Um mapeamento de formulário de ação que desativa a validação.


<action path="/download"
type="com.website.d2.action.DownloadAction"
name="downloadForm"
scope="request"
input=".download"
validate="false">
</action>

A desativação da validação expõe essa ação a vários tipos de ataques. A entrada não verificada é a causa raiz de vulnerabilidades como cross-site scripting, controle de processo e SQL injection. Embora os aplicativos J2EE geralmente não sejam suscetíveis a ataques de corrupção de memória, se um aplicativo J2EE faz interface com o código nativo que não executa a verificação de limite de array, um invasor pode ser capaz de usar um erro de validação de entrada no aplicativo J2EE para lançar um ataque de estouro de buffer (buffer overflow).
