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.
Bean Manipulation
Abstract
Um invasor pode definir propriedades de bean arbitrárias que podem comprometer a integridade do sistema.
Explanation
Nomes e valores de propriedades de bean precisam ser validados antes do preenchimento de qualquer bean. Funções de preenchimento de beans permitem que os desenvolvedores definam uma propriedade de bean ou uma propriedade aninhada. Os invasores podem utilizar essa funcionalidade para acessar propriedades especiais de beans, como
Exemplo: O código a seguir define uma propriedade de bean controlada pelo usuário sem a devida validação do nome da propriedade ou do valor:
class.classLoader, o que permitirá que ele substitua as propriedades do sistema e potencialmente execute código arbitrário.Exemplo: O código a seguir define uma propriedade de bean controlada pelo usuário sem a devida validação do nome da propriedade ou do valor:
String prop = request.getParameter('prop');
String value = request.getParameter('value');
HashMap properties = new HashMap();
properties.put(prop, value);
BeanUtils.populate(user, properties);
