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.

Mail Command Injection: IMAP

Java/JSP

Abstract

A execução de comandos IMAP provenientes de uma fonte não confiável pode fazer com que o servidor IMAP execute comandos mal-intencionados em nome de um invasor.

Explanation

Vulnerabilidades de injeção de comando IMAP ocorrem quando um invasor pode influenciar os comandos enviados a um servidor de e-mail IMAP.

1. Os dados entram em um aplicativo por uma fonte não confiável.

2. Os dados são usados como uma string, ou parte de uma string, que representa um comando executado pelo aplicativo.

3. Ao executar o comando IMAP, o invasor é capaz de instruir o servidor a realizar ações mal-intencionadas, como o envio de spam.

Exemplo 1: O código a seguir usa um parâmetro de solicitação HTTP para elaborar um comando CREATE que é enviado ao servidor IMAP. Um invasor pode usar esse parâmetro para modificar o comando enviado ao servidor e injetar novos comandos usando caracteres CRLF.


  ...
  final String foldername = request.getParameter("folder");
  IMAPFolder folder = (IMAPFolder) store.getFolder("INBOX");
  ...
  folder.doCommand(new IMAPFolder.ProtocolCommand() {
      @Override
      public Object doCommand(IMAPProtocol imapProtocol) throws ProtocolException {
          try {
              imapProtocol.simpleCommand("CREATE " + foldername, null);
          } catch (Exception e) {
              // Handle Exception
          }
          return null;
      }
  });
  ...
