界: Input Validation and Representation

輸入驗證和表示法問題是由中繼字元、替代編碼和數值表示法引起的。信任輸入會導致安全問題。問題包括：「Buffer Overflows」、「Cross-Site Scripting」攻擊、「SQL Injection」及其他許多問題。

Hadoop Cluster Manipulation

Java/JSP

Abstract

程式讓攻擊者可以控制用戶端應用程式執行所在的 Hadoop 叢集的核心元件。

Explanation

在以下情況會發生 Hadoop 叢集控制錯誤：

- 資料從一個不可信賴的來源進入程式。

- 資料被 Hadoop 叢集的核心元件例如 NameNode、DataNode、JobTraker 用來更改叢集的狀態。

Hadoop 叢集是不友善的環境。當未正確設定安全配置，無法防護未獲授權而存取叢集節點時，攻擊就有可能控制基礎架構。這可能造成 Hadoop 叢集提供的資料被竄改。

範例 1： 下列程式碼顯示一般用戶端應用程式中的 Job 提交，從 Hadoop 叢集主機器的指令行取其輸入資料：


  public static void run(String args[]) throws IOException {

    String path = "/path/to/a/file";
    DFSclient client = new DFSClient(arg[1], new Configuration());
    ClientProtocol nNode = client.getNameNode();

    /* This sets the ownership of a file pointed by the path to a user identified
     * by command line arguments.
     */
    nNode.setOwner(path, args[2], args[3]);
    ...
  }
