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.

Dynamic Code Evaluation: Unsafe XStream Deserialization

Java/JSP

Abstract

A desserialização de documentos XML controlados pelo usuário em tempo de execução pode permitir que os invasores executem um código arbitrário mal-intencionado no servidor.

Explanation

A biblioteca XStream fornece ao desenvolvedor uma maneira fácil de transmitir objetos, serializando-os para documentos XML. No entanto, a desserialização do XStream pode permitir que um invasor execute código Java arbitrário no servidor.

Exemplo 1: O código Java a seguir mostra uma instância de XStream processando uma entrada não confiável.


XStream xstream = new XStream();
String body = IOUtils.toString(request.getInputStream(), "UTF-8");
Contact expl = (Contact) xstream.fromXML(body);
