Android Misconfiguration: Debug Information

Java/JSP

Abstract

除錯訊息可幫助攻擊者了解系統並計劃攻擊形式。

Explanation

Android 應用程式可設定為產生除錯二進位程式。這些二進位程式提供了詳細的除錯訊息，不應該在生產的環境中使用。<application> 標籤的 debuggable 屬性定義編譯後的二進位程式是否應包含除錯資訊。

使用除錯二進位程式會使應用程式提供許多有關其本身的資訊給使用者。除錯二進位程式只能用於開發或測試的環境中，如果將它們部署在生產的環境中，會有安全上的風險。攻擊者可能利用這些從除錯輸出得到的額外資訊，來發動針對架構、資料庫或應用程式所使用的其他資源的攻擊。

Missing Check for Null Parameter

Java/JSP

Abstract

此函數必須將其參數與 null 作比較，但是卻違反了這個規定。

Explanation

Java 標準要求實作 Object.equals()、Comparable.compareTo() 和 Comparator.compare() 方法時，如果其參數為 null，則必須傳回指定的值。若沒有遵守這個規定，將會導致無法預期的結果。

範例 1：以下 equals() 方法的實作，不會將其參數與 null 比較。


public boolean equals(Object object)
{
   return (toString().equals(object.toString()));
}
