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: Unvalidated Action Form

Java/JSP

Abstract

Cada Formulário de Ação deve ter um formulário de validação correspondente.

Explanation

Se um mapeamento de formulário de ação do Struts especifica um formulário, ele deve ter um formulário de validação definido no Validador de Struts. Se um mapeamento de formulário de ação não tiver um formulário de validação definido, ele pode ser vulnerável a vários ataques que exploram uma entrada não verificada.

A entrada não verificada é a causa raiz de alguns dos piores e mais comuns problemas de segurança de software da atualidade. Vulnerabilidades de criação de script entre sites, SQL injection e controle de processos são todas derivadas de manipulações de entradas incompletas ou ausentes. 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).

Uma ação ou um formulário pode executar a validação de outras maneiras, mas o Struts Validator fornece uma excelente maneira de verificar se todas as entradas recebem pelo menos um nível básico de verificação. Sem essa abordagem, é difícil e, muitas vezes impossível, estabelecer com um alto nível de confiança que todas as entradas foram validadas.
